-Introduction
-------------
+# Introduction
 
-This is the README for **pv** ("Pipe Viewer"), a terminal-based tool for
-monitoring the progress of data through a pipeline.  It can be inserted into
-any normal pipeline between two processes to give a visual indication of how
-quickly data is passing through, how long it has taken, how near to
-completion it is, and an estimate of how long it will be until completion.
+**pv** ("Pipe Viewer") is a terminal-based tool for monitoring the progress
+of data through a pipeline and modifying its flow.
+
+When used just like "**cat**", **pv** displays how quickly data is being
+transferred, how long it has taken, how near to completion it is, and an
+estimate of how long it will be until completion.  Data flow rate, error
+handling strategy, buffer size, and cache interaction can all be adjusted.
+
+With the "**\--cursor**" option, several **pv** instances can work together,
+showing transfer progress at different points in the same pipeline.
+
+In "**\--watchfd**" mode, **pv** will inspect another process and show its
+progress through the files it has open.
+
+In "**\--monitor**" mode, **pv** will run a command and display the progress
+of data through both its standard input and its standard output.

-Compilation
------------
+# Installation
 
-If this is not a packaged release, first run "`./generate.sh`".
+See "[docs/INSTALL](./docs/INSTALL)" for more about the _configure_ script.
 
-To compile the package, type "`sh ./configure`", which should generate a
-Makefile for your system.  You may then type "`make`" to build everything.
-Note that GNU _make_ is required; this may be installed as _gmake_ on some
-systems, so if typing "`make`" gives an error, try "`gmake`" instead.
+The typical process for a system-wide install is:
 
-See the file "[doc/INSTALL](./doc/INSTALL)" for more about the _configure_ script.
+    sh ./configure --prefix=/usr
+    make
+    sudo make install
 
-Developers note that you can run "`./configure --enable-debugging`" to cause
-debugging support to be built in, and the `--enable-profiling` option builds
-in profiling support (see "`man gprof`").  Also note that running
-"`make index`" will generate an HTML code index (using _ctags_ and
-_cproto_); this index lists all files used, all functions defined, and all
-TODOs marked in the code.
+This requires the build toolchain ("`sudo apt install build-essential`" on
+Debian or Ubuntu systems).
+
+If this is not a packaged release, the _configure_ script is not included.
+It is generated with the GNU build system tools (_autoconf_, _aclocal_,
+_autopoint_, _automake_); _gettext_ is also needed.  On Debian or Ubuntu,
+run "`sudo apt install automake autopoint gettext`".  Once those tools are
+in place, call "`autoreconf -is`" to generate the _configure_ script, and
+run it as described above.

-[\fIFILE\fR]...
-.br
-.B @PACKAGE@
-[\fI\-h\fR|\fI\-V\fR]
-
-
-.SH DESCRIPTION
-.B @PACKAGE@
-shows the progress of data through a pipeline by giving information such as
-time elapsed, percentage completed (with progress bar), current throughput
-rate, total data transferred, and ETA.
-
-To use it, insert it in a pipeline between two processes, with the
-appropriate options.  Its standard input will be passed through to its
-standard output and progress will be shown on standard error.
-
-.B @PACKAGE@
-will copy each supplied
-.B FILE
-in turn to standard output
-.BR "" "(" -
-means standard input), or if no
-.BR FILE s
-are specified just standard input is copied. This is the same behaviour
-as
-.BR cat (1).
-
-A simple example to watch how quickly a file is transferred using
-.BR nc (1):
-
-.RS
-.B @PACKAGE@ file | nc -w 1 somewhere.com 3000
-.RE
-
-A similar example, transferring a file from another process and passing the
-expected size to
-.BR @PACKAGE@ :
-
-.RS
-.B cat file | @PACKAGE@ -s 12345 | nc -w 1 somewhere.com 3000
-.RE
-
-A more complicated example using numeric output to feed into the
-.BR dialog (1)
-program for a full-screen progress display:
- 
-.RS
-.B (tar cf - . \e
-.br
-.B " | @PACKAGE@ -n -s $(du -sb . | awk '{print $1}') \e"
-.br
-.B " | gzip -9 > out.tgz) 2>&1 \e"
-.br

-Note that if the input size cannot be calculated, and the output is a block
-device, then the size of the block device will be used and
-.B @PACKAGE@

-.SH OPTIONS
-.B @PACKAGE@
-takes many options, which are divided into display switches, output
-modifiers, and general options.
-
-
-.SH DISPLAY SWITCHES
-If no display switches are specified,
-.B @PACKAGE@
-behaves as if
-.BR \-p ", " \-t ", " \-e ", " \-r ", and " \-b
-had been given (i.e. everything except average rate is switched on).
-Otherwise, only those display types that are explicitly switched on will be
-shown.
-.TP
-.B \-p, \-\-progress
-Turn the progress bar on.  If standard input is not a file and no
-size was given (with the
-.B \-s
-modifier), the progress bar cannot indicate how close to completion the
-transfer is, so it will just move left and right to indicate that data is
-moving.
-.TP
-.B \-t, \-\-timer
-Turn the timer on.  This will display the total elapsed time that
-.B @PACKAGE@
-has been running for.
-.TP
-.B \-e, \-\-eta
-Turn the ETA timer on.  This will attempt to guess, based on current
-transfer rates and the total data size, how long it will be before
-completion.  This option will have no effect if the total data size cannot
-be determined.
-.TP
-.B \-I, \-\-fineta
-Turn the ETA timer on, but display the estimated local time of arrival
-instead of time left.  When the estimated time is more than 6 hours in the
-future, the date is shown as well.
-.TP
-.B \-r, \-\-rate
-Turn the rate counter on.  This will display the current rate of data
-transfer.
-.TP
-.B \-a, \-\-average\-rate
-Turn the average rate counter on.  This will display the current average
-rate of data transfer (default: last 30s, see --average-rate-window).
-.TP
-.B \-b, \-\-bytes
-Turn the total byte counter on.  This will display the total amount of
-data transferred so far.
-.TP
-.B \-8, \-\-bits
-Display the total bits instead of the total bytes.  The output suffix will
-be "b" instead of "B".
-.TP
-.B \-T, \-\-buffer\-percent
-Turn on the transfer buffer percentage display.  This will show the
-percentage of the transfer buffer in use - but see the caveat under
-.B %T
-in the
-.B FORMATTING
-section below.  Implies
-.BR \-C .
-.TP
-.B \-A, \-\-last\-written NUM
-Show the last
-.B NUM
-bytes written - but see the caveat under
-.B %nA
-in the
-.B FORMATTING
-section below.  Implies
-.BR \-C .
-.TP
-.B \-F, \-\-format FORMAT
-Ignore the options
-.BR \-p ,
-.BR \-t ,
-.BR \-e ,
-.BR \-r ,
-.BR \-a ,
-.BR \-b ,
-.BR \-T ,
-and
-.BR \-A ,
-and instead use the format string
-.B FORMAT
-to determine the output format.  See the
-.B FORMATTING
-section below.
-.TP
-.B \-n, \-\-numeric
-Numeric output.  Instead of giving a visual indication of progress,
-.B @PACKAGE@
-will give an integer percentage, one per line, on standard error, suitable
-for piping (via convoluted redirection) into
-.BR dialog (1).
-Note that
-.B \-f
-is not required if
-.B \-n
-is being used.
-.TP
-.B ""
-Note that if
-.B \-\-numeric
-is in use, then adding
-.B \-\-bytes
-will cause the number of bytes processed so far to be output instead of a
-percentage; if
-.B \-\-line\-mode
-is also in use, then instead of bytes or a percentage, the number of lines
-so far is output.  And finally, if
-.B \-\-timer
-is also in use, then each output line is prefixed with the elapsed time 
-so far, as a decimal number of seconds.
-.TP
-.B \-q, \-\-quiet
-No output.  Useful if the
-.B \-L
-option is being used on its own to just limit the transfer rate of a pipe.
-
-
-.SH OUTPUT MODIFIERS
-.TP
-.B \-W, \-\-wait
-Wait until the first byte has been transferred before showing any progress
-information or calculating any ETAs.  Useful if the program you are piping to
-or from requires extra information before it starts, eg piping data into
-.BR gpg (1)
-or
-.BR mcrypt (1)
-which require a passphrase before data can be processed.
-.TP
-.B \-D, \-\-delay-start SEC
-Wait until 
-.B SEC
-seconds have passed before showing any progress information, for example in
-a script where you only want to show a progress bar if it starts taking a
-long time.  Note that this can be a decimal such as 0.5.
-.TP
-.B \-s SIZE, \-\-size SIZE
-Assume the total amount of data to be transferred is
-.B SIZE
-bytes when calculating percentages and ETAs.  The same suffixes of "k", "m"
-etc can be used as with
-.BR -L .
-.TP
-.B ""
-If
-.B SIZE
-starts with
-.BR "@" ,
-the size of file whose name follows the
-.B @
-will be used.
-.TP
-.B ""
-Note that
-.B \-\-size
-has no effect if used with
-.B -d PID
-to watch all file descriptors of a process, but will work with
-.BR "-d PID:FD" .
-.TP
-.B \-l, \-\-line\-mode
-Instead of counting bytes, count lines (newline characters). The progress
-bar will only move when a new line is found, and the value passed to the
-.B \-s
-option will be interpreted as a line count.  Note that file sizes are not
-automatically calculated when this option is used, to avoid having to read
-all files twice.
-.TP
-.B \-0, \-\-null
-Count lines as null terminated.  This option implies \-\-line\-mode.
-.TP
-.B \-i SEC, \-\-interval SEC
-Wait
-.B SEC
-seconds between updates.  The default is to update every second.
-Note that this can be a decimal such as 0.1.
-.TP
-.B \-m SEC, \-\-average-rate-window SEC
-Compute current average rate over a
-.B SEC
-seconds window for average rate and ETA calculations (default 30s).
-.TP
-.B \-w WIDTH, \-\-width WIDTH
-Assume the terminal is
-.B WIDTH
-characters wide, instead of trying to work it out (or assuming 80 if it
-cannot be guessed).
-.TP
-.B \-H HEIGHT, \-\-height HEIGHT
-Assume the terminal is
-.B HEIGHT
-rows high, instead of trying to work it out (or assuming 25 if it
-cannot be guessed).
-.TP
-.B \-N NAME, \-\-name NAME
-Prefix the output information with
-.BR NAME .
-Useful in conjunction with
-.B \-c
-if you have a complicated pipeline and you want to be able to tell different
-parts of it apart.
-.TP
-.B \-f, \-\-force
-Force output.  Normally,
-.B @PACKAGE@
-will not output any visual display if standard error is not a terminal. 
-This option forces it to do so.
-.TP
-.B \-c, \-\-cursor
-Use cursor positioning escape sequences instead of just using carriage
-returns.  This is useful in conjunction with
-.B \-N
-(name) if you are using multiple
-.B @PACKAGE@
-invocations in a single, long, pipeline.
-
-
-.SH DATA TRANSFER MODIFIERS
-.TP
-.B \-L RATE, \-\-rate-limit RATE
-Limit the transfer to a maximum of
-.B RATE
-bytes per second.  A suffix of "K", "M", "G", or "T" can be added to denote
-kibibytes (*1024), mebibytes, and so on.
-.TP
-.B \-B BYTES, \-\-buffer-size BYTES
-Use a transfer buffer size of
-.B BYTES
-bytes.  A suffix of "K", "M", "G", or "T" can be added to denote
-kibibytes (*1024), mebibytes, and so on.  The default buffer size is the
-block size of the input file's filesystem multiplied by 32 (512KiB max), or
-400KiB if the block size cannot be determined.  This can be useful on
-platforms like MacOS which perform better in pipelines with specific buffer
-sizes such as 1024.  Implies
-.BR \-C .
-.TP
-.B \-C, \-\-no-splice
-Never use
-.BR splice (2),
-even if it would normally be possible.  The
-.BR splice (2)
-system call is a more efficient way of transferring data from or to a pipe
-than regular
-.BR read (2)
-and
-.BR write (2),
-but means that the transfer buffer may not be used.  This prevents
-.B \-A
-and
-.B \-T
-from working, and makes
-.B \-B
-redundant, so using
-.BR \-A ,
-.BR \-T ,
-or
-.B \-B
-automatically switches on
-.BR \-C .
-Switching on
-.B \-C
-results in a small loss of transfer efficiency.
-(This option has no effect on systems where
-.BR splice (2)
-is unavailable).
-.TP
-.B \-E, \-\-skip-errors
-Ignore read errors by attempting to skip past the offending sections.  The
-corresponding parts of the output will be null bytes.  At first only a few
-bytes will be skipped, but if there are many errors in a row then the skips
-will move up to chunks of 512.  This is intended to be similar to
-.B dd conv=sync,noerror
-but has not been as thoroughly tested.
-.TP
-.B ""
-Specify
-.B \-E
-twice to only report a read error once per file, instead of reporting each
-byte range skipped.
-.TP
-.B \-S, \-\-stop-at-size
-If a size was specified with
-.BR \-s ,
-stop transferring data once that many bytes have been written, instead of
-continuing to the end of input.
-.TP
-.B \-d PID[:FD], \-\-watchfd PID[:FD]
-Instead of transferring data, watch file descriptor
-.B FD
-of process
-.BR PID ,
-and show its progress.  The
-.B @PACKAGE@
-process will exit when
-.B FD
-either changes to a different file, changes read/write mode, or is closed;
-other data transfer modifiers - and remote control - may not be used with
-this option.
-.TP
-.B ""
-If only a
-.B PID
-is specified, then that process will be watched, and all regular files and
-block devices it opens will be shown with a progress bar.  The
-.B @PACKAGE@
-process will exit when process
-.B PID
-exits.
-.TP
-.B \-R PID, \-\-remote PID
-If
-.B PID
-is an instance of
-.B @PACKAGE@
-that is already running,
-.B \-R PID
-will cause that instance to act as though it had been given
-this instance's command line instead.  For example, if
-.B @PACKAGE@ -L 123K
-is running with process ID 9876, then running
-.B @PACKAGE@ -R 9876 -L 321K
-will cause it to start using a rate limit of 321KiB instead of 123KiB.
-Note that some options cannot be changed while running, such as
-.BR \-c ,
-.BR \-l ,
-.BR \-f ,
-.BR \-D ,
-.BR \-E ,
-and
-.BR \-S .
-
-.SH GENERAL OPTIONS
-.TP
-.B \-P FILE, \-\-pidfile FILE
-Save the process ID of
-.B @PACKAGE@
-in
-.BR FILE .
-The file will be truncated if it already exists, and will be removed when
-.B @PACKAGE@
-exits.  While
-.B @PACKAGE@
-is running, it will contain a single number - the process ID of
-.B @PACKAGE@
-- followed by a newline.
-.TP
-.B \-h, \-\-help
-Print a usage message on standard output and exit successfully.

-Print version information on standard output and exit successfully.
-
-
-.SH FORMATTING
-If the
-.B \-F
-option is given, then the output format is determined by the given format
-string.  Within that string, the following sequences can be used:
-.TP
-.B %p
-Progress bar.
-Expands to fill the remaining space. Should only be specified once.
-Equivalent to
-.BR \-p .
-.TP
-.B %t
-Elapsed time.  Equivalent to
-.BR \-t .
-.TP
-.B %e
-ETA as time remaining.  Equivalent to
-.BR \-e .
-.TP
-.B %I
-ETA as local time of completion.  Equivalent to
-.BR \-I .
-.TP
-.B %r
-Current data transfer rate.  Equivalent to
-.BR \-r .
-.TP
-.B %a
-Average data transfer rate.  Equivalent to
-.BR \-a .
-.TP
-.B %b
-Bytes transferred so far (or lines if
-.B \-l
-was specified).  Equivalent to
-.BR \-b .
-If
-.B \-\-bits
-was specified, 
-.B %b
-shows the bits transferred so far, not bytes.
-.TP
-.B %T
-Percentage of the transfer buffer in use.  Equivalent to
-.BR \-T .
-Shows "{----}" if the transfer is being done with
-.BR splice (2),
-since splicing to or from pipes does not use the buffer.
-.TP
-.B %nA
-Show the last 
-.B n
-bytes written (e.g.
-.B %16A
-for the last 16 bytes).
-Shows only dots if the transfer is being done with
-.BR splice (2),
-since splicing to or from pipes does not use the buffer.
-.TP
-.B %N
-Name prefix given by
-.BR -N .
-Padded to 9 characters with spaces, and suffixed with :.
-.TP
-.B %%
-A single %.
-.P
-The format string equivalent of turning on all display switches is
-.BR "\`%N %b %T %t %r %a %p %e'" .
-
-
-.SH COMMON SWITCHES
-Some suggested common switch combinations:
-
-.TP
-.B @PACKAGE@ -ptebar
-Show a progress bar, elapsed time, estimated completion time, byte counter,
-average rate, and current rate.
-.TP
-.B @PACKAGE@ -betlap
-Show a progress bar, elapsed time, estimated completion time, line counter,
-and average rate, counting lines instead of bytes.
-.TP
-.B @PACKAGE@ -t
-Show only the elapsed time - useful as a simple timer, e.g.
-.BR "sleep 10m | pv -t" .
-.TP
-.B @PACKAGE@ -pterb
-The default behaviour: progress bar, elapsed time, estimated completion
-time, current rate, and byte counter.
-
-.P
-On MacOS, it may be useful to specify
-.B -B 1024
-in a pipeline, as this may improve performance.
-
-
-.SH EXIT STATUS
-An exit status of 1 indicates a problem with the
-.B \-R
-or
-.B \-P
-options.
-
-Any other exit status is a bitmask of the following:
-
-.TP
-.B 2
-One or more files could not be accessed, 
-.BR stat (2)ed,
-or opened.
-.TP
-.B 4
-An input file was the same as the output file.
-.TP
-.B 8
-Internal error with closing a file or moving to the next file.
-.TP
-.B 16
-There was an error while transferring data from one or more input files.
-.TP
-.B 32

-
-.SH KNOWN PROBLEMS
-The following problems are known to exist in
-.BR @PACKAGE@ :
-.TP
-.B *
-In some versions of
-.BR bash (1)
-and
-.BR zsh (1),
-the construct
-.B <(pv filename)
-will not output any progress to the terminal when run from an interactive
-shell, due to the subprocess being run in a separate process group from the
-one that owns the terminal.  In these cases, use
-.BR \-\-force .
-.P
-.TP
-.B *
-The
-.B -c
-option does not work properly on Cygwin without
-.B cygserver
-running, if started near the bottom of the screen (IPC is needed to handle
-the terminal scrolling).  To fix this, start
-.B cygserver
-before using
-.BR "@PACKAGE@ -c" .
-.P
-.TP
-.B *
-The
-.B -R
-option is not available on Cygwin without
-.B cygserver
-running (SYSV IPC is needed). To fix this, start
-.B cygserver
-before running the instance of
-.B @PACKAGE@
-you want, at runtime, to change the parameters of.
-.P
-If you find any other problems, please report them.

+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<https://www.gnu.org/licenses/why-not-lgpl.html>.

+# Notes for developers and translators
+
+The following _configure_ options will be of interest to developers and
+translators:
+
+ * **--enable-debugging** - build in debugging support
+ * **--enable-profiling** - build in support for profiling
+
+These targets are available when running _make_:
+
+ * "`make analyse`" - run _splint_ and _flawfinder_ on all C source files
+
+
+## Debugging and profiling support
+
+When "`./configure --enable-debugging`" is used, the _pv_ produced by _make_
+will support an extra option, "**--debug FILE**", which will cause debugging
+output to be written to *FILE*.  This is not recommended for production
+builds due to the extra processing it introduces, and the potential size of
+the output.
+
+Within the code, "**debug()**" is used in a similar way to "**printf()**". 
+It will automatically include the calling function, source file, and line
+number, so they don't need to be included in the parameters.  When debugging
+support is not enabled, it evaluates to a null statement.
+
+This does mean that if you call "**debug()**", make sure it has no side
+effects, as they won't be present in builds without debugging support.
+
+Builds produced after "`./configure --enable-profiling`" will write profile
+data when run, to be used with _gprof_.  See "`man gprof`" for details. 
+Please note that the memory safety checks will fail with profiling enabled.
+
+
+## Source code analysis
+
+Running "`make analyse`" runs _splint_ and _flawfinder_ on all C sources,
+writing the output of both programs to files named _"*.e"_ for each _"*.c"_.
+
+There are no dependency rules set up for these _".e"_ files, so if a header
+file is altered, manually remove the relevant _".e"_ files, or update the
+timestamp of the relevant _".c"_ files, before running "`make analyse`"
+again.
+
+The goal is for all C source files to generate zero warnings from either
+tool.
+
+Wherever warnings are disabled by annotations to the source, there should be
+associated commentary nearby explaining the rationale behind it, and any
+assumptions made.  This is so that there can be some assurance that the
+issue highlighted by the analyser has been considered properly, as well as
+documenting anything that might need further work if the surrounding code is
+altered in future.
+
+
+## Translation notes
+
+Translators can use the Weblate instance hosted by Codeberg:
+[https://translate.codeberg.org/projects/pv/](https://translate.codeberg.org/projects/pv/)
+
+If you don't see your language listed, raise an issue on the issue tracker
+(or just email the maintainer) asking for it to be added.
+
+Alternatively, read on for details of how to maintain the translations
+directly within the source tree.
+
+The message catalogues used to translate program messages into other
+languages are in the _"po/"_ directory, named _"xx.po"_, where _"xx"_
+is the ISO 639-1 2-letter language code, such as "**fr**" for French.
+
+Each of these files contains lines like this:
+
+    #: src/pv/cursor.c:85
+    msgid "failed to get terminal name"
+    msgstr "erro ao ler o nome do terminal"
+
+The comment line, starting _"#"_, shows the source filename and line number
+at which this message can be found.  The _"msgid"_ is the original message
+in the program, in English.  The _"msgstr"_ is the translated text.
+
+It is the _"msgstr"_ lines which need to be updated by translators.
+
+Message catalogue files should all be encoded as UTF-8.
+
+After making a change to a _".po"_ file, test it by compiling it and
+installing to a temporary location, like this:
+
+    ./configure --enable-debugging --prefix=/tmp/yourtest
+    make clean
+    make install
+    localedef -f UTF-8 -i de_DE /tmp/yourtest/share/locale/de_DE.UTF-8
+    bash
+    export LOCPATH=/tmp/yourtest/share/locale
+    export LC_ALL=de_DE.UTF-8
+    export LANGUAGE=de_DE
+    /tmp/yourtest/bin/pv --help
+    exit
+
+Replace "**--help**" with whatever is appropriate for your test.  In this
+example, the language being tested is _"de"_ (German), on a system which is
+running with UTF-8 support.
+
+In the example above, a new shell is started by typing "`bash`" so that
+after your tests, "`exit`" will return you to your previous shell with your
+language settings intact.
+
+Note that at the start, you have to re-run _configure_ with "**--prefix**"
+rather than using "`make DESTDIR=...`", because the locale directory is set
+at compile time.  Also, on Debian at least, both the environment variables
+_"LC_ALL"_ and _"LANGUAGE"_ must be set.
+
+To find untranslated strings in a language that's already supported but
+which you can help with gaps in, use this command:
+
+    msgattrib --untranslated < po/fr.po
+
+replacing _"po/fr.po"_ as appropriate.
+
+To add a new language, create the new message catalogue file under _"po/"_
+by copying _"po/pv.pot"_ to _"po/xx.po"_, where _"xx"_ is the language code,
+and adjusting it.  The _".pot"_ file is generated automatically by _make_.
+
+Next, add the language code to _"po/LINGUAS"_ - this is a list of the
+2-letter codes of the supported languages.
+
+Finally, run "`./config.status`" and "`make -C po update-po`".
+
+When the source code is updated, running "`make -C po update-po`" will
+update the _"pv.pot"_ file so that it lists where all the messages are in
+the source.  It will also use _msgmerge_ to update all of the _".po"_ files
+from the updated _"pv.pot"_ file.  After doing this, look for missing
+translations (empty _"msgstr"_ lines) or translations marked as "fuzzy", as
+these will need to be corrected by translators.
+
+
+## Benchmarking
+
+The "`docs/benchmark-pv-transfers.sh`" script, introduced in
+[#198](https://codeberg.org/ivarch/pv/issues/198), is used to check that new
+changes to **pv** aren't making it less efficient at transferring data.  Run
+it with the **--help** option for a summary of its options.
+
+In _benchmark_ mode, it takes multiple rounds of measurements of the
+transfer rate using various different transfer options.  The mean (μ) and
+standard deviation (σ) of each measurement is produced at the end of the
+run.  All data is written to the standard output - pipe to "`tee OUTPUT`" to
+write to a file _OUTPUT_ while still displaying it on the terminal.
+
+Either a specific **pv** binary can be benchmarked (with the **-p** option),
+or multiple **pv** versions can be benchmarked in a single call, each one
+counting as an individual run (with the **-d** option, pointing to a
+directory containing _tar.gz_ source archives).
+
+Transfer rate measurements use up to two test files, the size of which can
+be overridden by the **-s** option, and some measurements will transfer and
+discard zeros from _/dev/zero_, the amount of which can be overridden with
+the **-z** option.
+
+The measured rates may vary significantly due to external factors such as
+system load, so multiple measurement rounds (the **-r** option) are
+recommended per run.
+
+In _analyse_ mode, the results of multiple runs are read from standard
+input, and a report is produced that shows how each measurement differs
+between runs.
+
+If the input data is from multiple versions of **pv**, the differences
+between versions will be compared; otherwise, the differences between
+individual runs will be compared.  The **-c** option overrides this.
+
+When re-using data from multiple runs, the **-f** option causes the report
+to only show the differences between the last two runs (or versions).
+
+The **-t** option produces a terse report that is more machine-readable.
+
+In _measurements_ mode, a list of all of the measurement types is produced.
+Each type of measurement has an associated ID - these IDs can be passed to
+the benchmark mode to only run a subset of the measurements in that run.
+
+

+.\"
+.SH DESCRIPTION
+Show the progress of data through a pipeline by giving information such as
+time elapsed, percentage completed (with progress bar), current throughput
+rate, total data transferred, and ETA.
+The data flow rate, error handling strategy, buffer size, and cache
+interaction can all be adjusted.
+.PP
+Each \fIFILE\fR is copied to standard output.
+With no \fIFILE\fR, or when \fIFILE\fR is \*(lq-\*(rq, standard input is
+read.
+.PP
+In \*(lq\fB\-\-watchfd\fR\*(rq mode, inspect another process and show its
+progress through the files it has open.
+.PP
+In \*(lq\fB\-\-monitor\fR\*(rq mode, run a command and display the progress
+of data through both its standard input and its standard output.
+.\"
+.SH OPTIONS
+.\"
+.SS "Display switches"
+If no display switches are specified, \fBpv\fR behaves as if
+\*(lq\fB\-\-progress\fR\*(rq, \*(lq\fB\-\-timer\fR\*(rq,
+\*(lq\fB\-\-eta\fR\*(rq, \*(lq\fB\-\-rate\fR\*(rq, and
+\*(lq\fB\-\-bytes\fR\*(rq had been given.
+Otherwise, only those display types that are explicitly switched on will be
+shown.
+.TP
+.B \-p, \-\-progress
+Turn the progress bar on.
+If any inputs are not files, or are unreadable, and no size was explicitly
+given with \*(lq\fB\-\-size\fR\*(rq, the progress bar cannot indicate how
+close to completion the transfer is, so it will just move left and right to
+indicate that data is moving - or, with \*(lq\fB\-\-gauge\fR\*(rq, the bar
+will indicate the current rate as a percentage of the maximum rate seen so
+far.
+.TP
+.B \-t, \-\-timer
+Turn the timer on.
+This will display the total elapsed time that \fBpv\fR has been running for.
+.TP
+.B \-e, \-\-eta
+Turn the ETA countdown on.
+This will estimate, based on current transfer rates and the total data size,
+how long it will be before completion.
+The countdown is prefixed with \*(lqETA\*(rq.
+This option will have no effect if the total data size cannot be determined.
+.TP
+.B \-I, \-\-fineta
+Turn the ETA countdown on, but display the estimated local time at which the
+transfer will finish, instead of the amount of time remaining.
+When the estimated time is more than 6 hours in the future, the date is
+shown as well.
+The time is prefixed with \*(lqFIN\*(rq for finish time.
+As with \*(lq\fB\-\-eta\fR\*(rq, this option will have no effect if the
+total data size cannot be determined.
+.TP
+.B \-r, \-\-rate
+Turn the rate counter on.
+This will display the current rate of data transfer.
+The rate is shown in square brackets \*(lq[]\*(rq.
+.TP
+.B \-a, \-\-average\-rate
+Turn the average rate counter on.
+This will display the current average rate of data transfer, over the last
+30 seconds by default (see \*(lq\fB\-\-average-rate-window\fR\*(rq).
+The average rate is shown in brackets \*(lq()\*(rq.
+.TP
+.B \-b, \-\-bytes
+Turn the total byte counter on.
+This will display the total amount of data transferred so far.
+.TP
+.B \-T, \-\-buffer\-percent
+Turn on the transfer buffer percentage display.
+This will show the percentage of the transfer buffer in use.
+Implies \*(lq\fB\-\-no\-splice\fR\*(rq.
+The transfer buffer percentage is shown in curly brackets \*(lq{}\*(rq.
+.TP
+.BI \-A\  NUM \fR,\ \fB\-\-last\-written\  NUM
+Show the last \fINUM\fR bytes written.
+Implies \*(lq\fB\-\-no\-splice\fR\*(rq.
+.TP
+.BI \-F\  FORMAT \fR,\ \fB\-\-format\  FORMAT
+Ignore all of the above options and instead use the format string
+\fIFORMAT\fR to determine the output format.
+See the \fBFORMATTING\fR section below.
+.TP
+.B \-n, \-\-numeric
+Numeric output.
+Instead of giving a visual indication of progress, write an integer
+percentage, one per line, on standard error, suitable for passing to a tool
+such as \fBdialog\fR(1).
+Note that \*(lq\fB\-\-force\fR\*(rq is not required if
+\*(lq\fB\-\-numeric\fR\*(rq is being used.
+.IP
+Combining \*(lq\fB\-\-numeric\fR\*(rq with \*(lq\fB\-\-bytes\fR\*(rq will
+cause the number of bytes processed so far to be output instead of a
+percentage.
+Adding \*(lq\fB\-\-line\-mode\fR\*(rq as well as \*(lq\fB\-\-bytes\fR\*(rq
+writes the number of lines instead of bytes or a percentage.
+Adding \*(lq\fB\-\-rate\fR\*(rq adds the transfer rate to each output line
+(if \*(lq\fB\-\-bytes\fR\*(rq is also in use, the rate comes after the
+byte/line count).
+Adding \*(lq\fB\-\-timer\fR\*(rq prefixes each output line with the elapsed
+time so far, as a decimal number of seconds.
+.IP
+Combining \*(lq\fB\-\-numeric\fR\*(rq with \*(lq\fB\-\-format\fR\*(rq allows
+for custom output.  The default format string components for
+\*(lq\fB\-\-numeric\fR\*(rq are
+\*(lq\fB%t\~%b\~%r\~%{progress\-amount\-only}\fR\*(rq in that order, each
+item being active or inactive according to the rules above (so the default
+with no other options is \*(lq\fB%{progress\-amount\-only}\fR\*(rq).
+.TP
+.B \-q, \-\-quiet
+No output.
+Useful if the \*(lq\fB\-\-rate\-limit\fR\*(rq option is being used on its
+own to limit the transfer rate of a pipe.
+.\"
+.SS "Output modifiers"
+.TP
+.B \-8, \-\-bits
+Use bits instead of bytes for the byte and rate counters.
+The output suffix will be \*(lqb\*(rq instead of \*(lqB\*(rq.
+.TP
+.B \-k, \-\-si
+Display and interpret suffixes as multiples of 1000 rather than the default
+of 1024.
+Note that this only takes effect on options after this one, so for
+consistency, specify this option first.
+.TP
+.B \-W, \-\-wait
+Wait until the first byte has been transferred before showing any progress
+information or calculating any ETAs.
+For example, use this option when piping data into tools such as
+\fBgpg\fR(1) or \*(lq\fBmysql\~\-p\fR\*(rq so the count only starts after
+the password prompt has been answered.
+.TP
+.BI \-D\  SEC \fR,\ \fB\-\-delay\-start\  SEC
+Wait until \fISEC\fR seconds have passed before showing any progress
+information, so that a transfer that is over quickly won't display anything.
+The value of \fISEC\fR can be a decimal such as \*(lq0.5\*(rq.
+.TP
+.BI \-s\  SIZE \fR,\ \fB\-\-size\  SIZE
+Assume the total amount of data to be transferred is \fISIZE\fR bytes when
+calculating percentages and ETAs.
+A suffix of \*(lqK\*(rq, \*(lqM\*(rq, \*(lqG\*(rq, or \*(lqT\*(rq can be
+added to denote kibibytes (*1024), mebibytes, gibibytes, tebibytes.
+If \*(lq\fB\-\-si\fR\*(rq appears before this option, suffixes will denote
+kilobytes (*1000), megabytes, and so on instead.
+.IP
+If \fISIZE\fR starts with \*(lq\fB@\fR\*(rq, the size of file whose name
+follows the @ will be used; if that is a directory, the size of all files
+under it will be used, like \*(lq\fBdu\~\-\-apparent\-size\~\-b\fR\*(rq.
+.TP
+.B \-g, \-\-gauge
+If the progress bar is shown but the size is not known, then instead of
+moving the bar left and right to show progress, show the current transfer
+rate as a percentage of the maximum rate seen so far.
+.TP
+.B \-l, \-\-line\-mode
+Instead of counting bytes, count lines (newline characters).
+The progress bar will only move when a new line is found, and the value
+passed to \*(lq\fB\-\-size\fR\*(rq will be interpreted as a line count.
+.IP
+If this option is used without \*(lq\fB\-\-size\fR\*(rq, the "total size"
+(in this case, total line count) is calculated by reading through all input
+files once before transfer starts.
+If any inputs are pipes or non-regular files, or are unreadable, the total
+size will not be calculated.
+.TP
+.B \-0, \-\-null
+Count lines as terminated with a null byte instead of with a newline.
+This option implies \*(lq\fB\-\-line\-mode\fR\*(rq.
+.TP
+.BI \-i\  SEC \fR,\ \fB\-\-interval\  SEC
+Wait \fISEC\fR seconds between updates.
+The default is to update every second.
+The value of \fISEC\fR can be a decimal such as \*(lq0.1\*(rq.
+.TP
+.BI \-m\  SEC \fR,\ \fB\-\-average-rate-window\  SEC
+Compute current average rate over a \fISEC\fR seconds window for average
+rate and ETA calculations.
+The default is 30 seconds.
+The value must be an integer.
+.TP
+.BI \-w\  WIDTH \fR,\ \fB\-\-width\  WIDTH
+Assume the terminal is \fIWIDTH\fR columns wide, instead of autodetecting
+the width (or assuming 80 if detection fails).
+If this option is used, the output width will not be adjusted if the width
+of the terminal changes while the transfer is running.
+.TP
+.BI \-H\  HEIGHT \fR,\ \fB\-\-height\  HEIGHT
+Assume the terminal is \fIHEIGHT\fR rows high, instead of autodetecting
+the height (or assuming 25 if detection fails).
+If this option is used, the output height will not be adjusted if the height
+of the terminal changes while the transfer is running.
+.TP
+.BI \-N\  NAME \fR,\ \fB\-\-name\  NAME
+Prefix the output information with \fINAME\fR.
+Often used with \*(lq\fB\-\-cursor\fR\*(rq to identify each progress bar in
+a pipeline containing more than one \fBpv\fR.
+.TP
+.BI \-u\  STYLE \fR,\ \fB\-\-bar\-style\  STYLE
+Change the default progress bar style shown by \*(lq\fB\-\-progress\fR\*(rq,
+or by the \*(lq\fB\-\-format\fR\*(rq sequences \*(lq\fB%{progress}\fR\*(rq
+or \*(lq\fB%{progress\-bar\-only}\fR\*(rq, to \fISTYLE\fR.
+The \fISTYLE\fR can be one of \fBplain\fR (the default), \fBblock\fR,
+\fBgranular\fR, or \fBshaded\fR.
+These styles are described in the \fBFORMATTING\fR section below.
+.TP
+.BI \-x\  SPEC \fR,\ \fB\-\-extra\-display\  SPEC
+As well as displaying progress to the terminal, also write it to \fISPEC\fR.
+The \fISPEC\fR must start with a comma-separated list of destinations, and
+can optionally be followed by a colon and a format string.
+The destinations can be \fBwindowtitle\fR or \fBwindow\fR for the xterm
+window title, and \fBprocesstitle\fR, \fBproctitle\fR, \fBprocess\fR, or
+\fBproc\fR for the process title displayed by \fBps\fR(1).
+If a format string is not supplied, the same format is used as for the
+terminal.
+For example, \*(lq\fB\-x\~'window,process:%t\~%b\~%r'\fR\*(rq will show the
+elapsed time, bytes transferred, and rate, in both the window title and the
+process title.
+.TP
+.B \-v, \-\-stats
+At the end of the transfer, write an additional line showing the transfer
+rate minimum, mean, maximum, and standard deviation.
+The values are always in bytes per second (or bits, with
+\*(lq\fB\-\-bits\fR\*(rq).
+.TP
+.B \-f, \-\-force
+Force output.
+Normally, \fBpv\fR will not output any visual display if standard error is
+not a terminal.
+This option forces it to do so.
+.TP
+.B \-c, \-\-cursor
+Use cursor positioning escape sequences to move to the initial terminal row
+when updating the display, instead of only using carriage returns.
+This allows multiple \fBpv\fR instances to show progress on the same
+terminal together.
+.IP
+For example:
+.IP
+.in +4
+.EX
+pv --cursor --name input file.gz | gzip -d | pv --cursor --name output > file
+.EE
+.in
+.IP
+As the example shows, this is often used with \*(lq\fB\-\-name\fR\*(rq.
+.\"
+.SS "Data transfer modifiers"
+.TP
+.BI \-o\  FILE \fR,\ \fB\-\-output\  FILE
+Write data to \fIFILE\fR instead of standard output.
+If the file already exists, it will be truncated.
+.TP
+.BI \-L\  RATE \fR,\ \fB\-\-rate-limit\  RATE
+Limit the transfer to a maximum of \fIRATE\fR bytes per second.
+The same suffixes as \*(lq\fB\-\-size\fR\*(rq can be used.
+Decimal values are allowed.
+Specifying 0 will turn off rate limiting, which is useful with
+\*(lq\fB\-\-remote\fR\*(rq.
+.TP
+.BI \-B\  BYTES \fR,\ \fB\-\-buffer-size\  BYTES
+Use a transfer buffer size of \fIBYTES\fR bytes.
+The same suffixes as \*(lq\fB\-\-size\fR\*(rq can be used.
+The default buffer size is the block size of the input file's filesystem
+multiplied by 32 (512KiB max), or 400KiB if the block size cannot be
+determined.
+This can be useful on platforms like macOS with pipelines that perform
+better with specific buffer sizes such as 1024.
+Implies \*(lq\fB\-\-no\-splice\fR\*(rq.
+.TP
+.B \-C, \-\-no-splice
+Prevent the use of \fBsplice\fR(2) and \fBcopy_file_range\fR(2), which are
+normally used on systems that support it to improve efficiency by
+eliminating the need for a transfer buffer.
+.IP
+In the default case that \fBsplice\fR(2) or \fBcopy_file_range\fR(2) are
+used, the lack of a transfer buffer prevents
+\*(lq\fB\-\-buffer\-percent\fR\*(rq and
+\*(lq\fB\-\-last\-written\fR\*(rq from working and makes
+\*(lq\fB\-\-buffer\-size\fR\*(rq redundant, so using any of those options
+automatically switches on \*(lq\fB\-\-no\-splice\fR\*(rq.
+.IP
+Sparse files cannot be written with \fBsplice\fR(2) or
+\fBcopy_file_range\fR(2), so using
+\*(lq\fB\-\-sparse\fR\*(rq automatically switches on
+\*(lq\fB\-\-no\-splice\fR\*(rq.
+.IP
+Switching on \*(lq\fB\-\-no\-splice\fR\*(rq results in a small loss of
+transfer efficiency.
+It has no effect on systems where \fBsplice\fR(2) and
+\fBcopy_file_range\fR(2) are unavailable.
+.TP
+.BI \-J\  BYTES \fR,\ \fB\-\-pipe\-buffer\-size\  BYTES
+Attempt to set the size of the output pipe buffer, and the intermediate
+input pipe buffer if one is needed, to \fIBYTES\fR bytes.
+This will silently do nothing if the requested size cannot be achieved.
+If this option is not specified, and both the output and the first input are
+pipes, then the output pipe buffer size will automatically be increased to
+match the input pipe buffer, if it was smaller.
+.TP
+.B \-E, \-\-skip-errors
+Ignore read errors by attempting to skip past the offending sections.
+The corresponding parts of the output will be null bytes.
+At first only a few bytes will be skipped, but if there are many errors in a
+row then the skips will move up to chunks of 512.
+This is intended to be similar to \*(lq\fIdd\~conv=sync,noerror\fR\*(rq.
+.IP
+Specify \*(lq\fB\-\-skip\-errors\fR\*(rq twice to only report a read error
+once per file, instead of reporting each byte range skipped.
+.TP
+.BI \-Z\  BYTES \fR,\ \fB\-\-error\-skip\-block\  BYTES
+When ignoring read errors with \*(lq\fB\-\-skip\-errors\fR\*(rq, instead of
+trying to adaptively skip by reading small amounts and skipping
+progressively larger sections until a read succeeds, move to the next file
+block of \fIBYTES\fR bytes as soon as an error occurs.
+There may still be some shorter skips where the block being skipped
+coincides with the end of the transfer buffer.
+The same suffixes as \*(lq\fB\-\-size\fR\*(rq can be used.
+.IP
+This option can only be used with \*(lq\fB\-\-skip\-errors\fR\*(rq
+and is intended for use when reading from a block device, such as
+\*(lq\fB\-\-skip\-errors\~\-\-error\-skip\-block\~4K\fR\*(rq
+to skip in 4 kibibyte blocks.
+This will speed up reads from faulty media, at the expense of potentially
+losing more data.
+.TP
+.B \-S, \-\-stop-at-size
+If a size was specified with \*(lq\fB\-\-size\fR\*(rq, stop transferring
+data once that many bytes have been written, instead of continuing to the
+end of input.
+.TP
+.B \-Y, \-\-sync
+After every write operation, synchronise the buffer caches to disk with
+\fBsync\fR(2), or \fBfdatasync\fR(2) if possible.
+This has no effect when the output is a pipe.
+Using \*(lq\fB\-\-sync\fR\*(rq may improve the accuracy of the progress bar
+when writing to a slow disk.
+.TP
+.B \-K, \-\-direct-io
+Set the \fBO_DIRECT\fR flag on all inputs and outputs, if it is available.
+This will minimise the effect of caches, at the cost of performance.
+Due to memory alignment requirements, it also may cause read or write
+failures with an error of \*(lqInvalid argument\*(rq, especially if reading
+and writing files across a variety of filesystems in a single \fBpv\fR call.
+Use this option with caution.
+.TP
+.B \-O, \-\-sparse
+When writing null bytes, try to seek, producing a sparse output file.
+Implies \*(lq\fB\-\-no\-splice\fR\*(rq.
+On filesystems without sparse file support, or when the output is not
+seekable, this option will have no effect other than to turn on
+\*(lq\fB\-\-no\-splice\fR\*(rq.
+.TP
+.B \-X, \-\-discard
+Instead of transferring input data to standard output, discard it.
+This is equivalent to redirecting standard output to \fI/dev/null\fR,
+except that \fBwrite\fR(2) is never called.
+.TP
+.BI \-U\  FILE \fR,\ \fB\-\-store\-and\-forward\  FILE
+Instead of passing data through immediately, do it in two stages - first
+read all input and write it to \fIFILE\fR, and then once the input is
+exhausted, read all of \fIFILE\fR and write it to the output.
+\fIFILE\fR remains in place afterwards, unless it is
+\*(lq\fB-\fR\*(rq, in which case \fBpv\fR creates a temporary file for this
+purpose, and automatically removes it afterwards.
+.IP
+A common use for this is this where one part of a pipeline generates data
+quickly but of unknown size, and the next part processes it slowly.
+With \*(lq\fIquick\fR\~\fB|\~pv\~\-U\~\-\~|\fR\~\fIslow\fR\*(rq, a progress
+bar is displayed with unknown size for the \fIquick\fR part, then a second
+is shown with a known size and ETA for the \fIslow\fR part.

+\fIPID\fR, and show its progress.
+Other data transfer modifiers - and remote control - may not be used with
+this option.
+.IP
+If a \fIPID\fR is specified without an \fIFD\fR, then that process will be

+For example,

+.\"
+.SH NOTES
+In some versions of \fBbash\fR(1) and \fBzsh\fR(1), the construct
+\*(lq\fB<(pv\~filename)\fR\*(rq will not output any progress to the terminal
+when run from an interactive shell, due to the subprocess being run in a
+separate process group from the one that owns the terminal.
+In these cases, use \*(lq\fB\-\-force\fR\*(rq.
+.PP
+If \fBpv\fR is used in a pipeline in \fBzsh\fR version 5.8, and the last
+command in the pipeline is based on shell builtins, \fBzsh\fR takes control
+of the terminal away from \fBpv\fR, preventing progress from being
+displayed.
+For example, this will produce no progress bar:
+.PP
+.in +4n
+.EX
+pv InputFile | { while read \-r line; do sleep 0.1; done; }
+.EE
+.in
+.PP
+To work around this, put the last commands of the pipeline in
+normal brackets to force the use of a subshell:
+.PP
+.in +4n
+.EX
+pv InputFile | ( while read \-r line; do sleep 0.1; done; )
+.EE
+.in
+.PP
+Refer to
+.UR https://codeberg.org/ivarch/pv/issues/105
+issue #105
+.UE
+for full details.
+.PP
+The \*(lq\fB\-\-remote\fR\*(rq and \*(lq\fB\-\-query\fR\*(rq options require
+that either \fI/run/user/<uid>/\fR or \fI$HOME/\fR can be written to, for
+inter-process communication.
+.PP
+The \*(lq\fB\-\-size\fR\*(rq option has no effect if used with
+\*(lq\fB\-\-watchfd\fR\~\fIPID\fR\*(rq to watch all file descriptors of a
+process, but will work with \*(lq\fB\-\-watchfd\fR\~\fIPID\fR:\fIFD\fR\*(rq
+to watch a single file descriptor.
+.PP
+If the input size cannot be calculated, and the output is a block device,
+then \fBpv\fR will read the output device's size, use that as if it had been
+passed to \*(lq\fB\-\-size\fR\*(rq, and activate
+\*(lq\fB\-\-stop\-at\-size\fR\*(rq.
+.PP
+The \*(lq\fB%nA\fR\*(rq and \*(lq\fB%nL\fR\*(rq format sequences may not be
+effective with small input files, and \*(lq\fB%nL\fR\*(rq may be a few lines
+out due to buffering within the pipeline itself.
+.PP
+Numbers passed to \*(lq\fB\-\-size\fR\*(rq,
+\*(lq\fB\-\-buffer\-size\fR\*(rq, \*(lq\fB\-\-pipe\-buffer\-size\fR\*(rq,
+and \*(lq\fB\-\-error\-skip\-block\fR\*(rq may all be expressed as decimals
+if followed by a suffix, so for example \*(lq\fI\-\-size\~1.5G\fR\*(rq is
+equivalent to \*(lq\fI\-\-size\~1536M\fR\*(rq.
+.PP
+Numbers passed to \*(lq\fB\-\-rate\-limit\fR\*(rq may be expressed as
+decimals with or without a suffix.
+.PP
+Numbers passed to \*(lq\fB\-\-interval\fR\*(rq and
+\*(lq\fB\-\-delay\-start\fR\*(rq may be integers or decimals, but may not
+have a suffix.
+.PP
+Numbers passed to \*(lq\fB\-\-last\-written\fR\*(rq,
+\*(lq\fB\-\-width\fR\*(rq, \*(lq\fB\-\-height\fR\*(rq,
+\*(lq\fB\-\-average\-rate\-window\fR\*(rq, \*(lq\fB\-\-remote\fR\*(rq, and
+\*(lq\fB\-\-query\fR\*(rq must be integers with no suffix.
+.PP
+When \*(lq\fB\-\-sparse\fR\*(rq is in effect and output is being written to
+a file, that file may look like it has stopped growing if inspected with
+\fBls\fR(1) while null bytes are being written, even though \fBpv\fR still
+reports progress.
+This is because of the way sparse output is achieved, and the file will be
+the correct size when the transfer ends.

+# DESCRIPTION
+
+Show the progress of data through a pipeline by giving information such
+as time elapsed, percentage completed (with progress bar), current
+throughput rate, total data transferred, and ETA. The data flow rate,
+error handling strategy, buffer size, and cache interaction can all be
+adjusted.
+
+Each *FILE* is copied to standard output. With no *FILE*, or when *FILE*
+is "-", standard input is read.
+
+In "**\--watchfd**" mode, inspect another process and show its progress
+through the files it has open.
+
+In "**\--monitor**" mode, run a command and display the progress of data
+through both its standard input and its standard output.
+
+# OPTIONS
+
+## Display switches
+
+If no display switches are specified, **pv** behaves as if
+"**\--progress**", "**\--timer**", "**\--eta**", "**\--rate**", and
+"**\--bytes**" had been given. Otherwise, only those display types that
+are explicitly switched on will be shown.
+
+**-p, \--progress**
+
+:   Turn the progress bar on. If any inputs are not files, or are
+    unreadable, and no size was explicitly given with "**\--size**", the
+    progress bar cannot indicate how close to completion the transfer
+    is, so it will just move left and right to indicate that data is
+    moving - or, with "**\--gauge**", the bar will indicate the current
+    rate as a percentage of the maximum rate seen so far.
+
+**-t, \--timer**
+
+:   Turn the timer on. This will display the total elapsed time that
+    **pv** has been running for.
+
+**-e, \--eta**
+
+:   Turn the ETA countdown on. This will estimate, based on current
+    transfer rates and the total data size, how long it will be before
+    completion. The countdown is prefixed with "ETA". This option will
+    have no effect if the total data size cannot be determined.
+
+**-I, \--fineta**
+
+:   Turn the ETA countdown on, but display the estimated local time at
+    which the transfer will finish, instead of the amount of time
+    remaining. When the estimated time is more than 6 hours in the
+    future, the date is shown as well. The time is prefixed with "FIN"
+    for finish time. As with "**\--eta**", this option will have no
+    effect if the total data size cannot be determined.
+
+**-r, \--rate**
+
+:   Turn the rate counter on. This will display the current rate of data
+    transfer. The rate is shown in square brackets "\[\]".
+
+**-a, \--average-rate**
+
+:   Turn the average rate counter on. This will display the current
+    average rate of data transfer, over the last 30 seconds by default
+    (see "**\--average-rate-window**"). The average rate is shown in
+    brackets "()".
+
+**-b, \--bytes**
+
+:   Turn the total byte counter on. This will display the total amount
+    of data transferred so far.
+
+**-T, \--buffer-percent**
+
+:   Turn on the transfer buffer percentage display. This will show the
+    percentage of the transfer buffer in use. Implies
+    "**\--no-splice**". The transfer buffer percentage is shown in curly
+    brackets "{}".
+
+**-A NUM, \--last-written NUM**
+
+:   Show the last *NUM* bytes written. Implies "**\--no-splice**".
+
+**-F FORMAT, \--format FORMAT**
+
+:   Ignore all of the above options and instead use the format string
+    *FORMAT* to determine the output format. See the **FORMATTING**
+    section below.
+
+**-n, \--numeric**
+
+:   Numeric output. Instead of giving a visual indication of progress,
+    write an integer percentage, one per line, on standard error,
+    suitable for passing to a tool such as **dialog**(1). Note that
+    "**\--force**" is not required if "**\--numeric**" is being used.
+
+    Combining "**\--numeric**" with "**\--bytes**" will cause the number
+    of bytes processed so far to be output instead of a percentage.
+    Adding "**\--line-mode**" as well as "**\--bytes**" writes the
+    number of lines instead of bytes or a percentage. Adding
+    "**\--rate**" adds the transfer rate to each output line (if
+    "**\--bytes**" is also in use, the rate comes after the byte/line
+    count). Adding "**\--timer**" prefixes each output line with the
+    elapsed time so far, as a decimal number of seconds.
+
+    Combining "**\--numeric**" with "**\--format**" allows for custom
+    output. The default format string components for "**\--numeric**"
+    are "**%t %b %r %{progress-amount-only}**" in that order, each item
+    being active or inactive according to the rules above (so the
+    default with no other options is "**%{progress-amount-only}**").
+
+**-q, \--quiet**
+
+:   No output. Useful if the "**\--rate-limit**" option is being used on
+    its own to limit the transfer rate of a pipe.
+
+## Output modifiers
+
+**-8, \--bits**
+
+:   Use bits instead of bytes for the byte and rate counters. The output
+    suffix will be "b" instead of "B".
+
+**-k, \--si**
+
+:   Display and interpret suffixes as multiples of 1000 rather than the
+    default of 1024. Note that this only takes effect on options after
+    this one, so for consistency, specify this option first.
+
+**-W, \--wait**
+
+:   Wait until the first byte has been transferred before showing any
+    progress information or calculating any ETAs. For example, use this
+    option when piping data into tools such as **gpg**(1) or
+    "**mysql -p**" so the count only starts after the password prompt
+    has been answered.
+
+**-D SEC, \--delay-start SEC**
+
+:   Wait until *SEC* seconds have passed before showing any progress
+    information, so that a transfer that is over quickly won\'t display
+    anything. The value of *SEC* can be a decimal such as "0.5".
+
+**-s SIZE, \--size SIZE**
+
+:   Assume the total amount of data to be transferred is *SIZE* bytes
+    when calculating percentages and ETAs. A suffix of "K", "M", "G", or
+    "T" can be added to denote kibibytes (\*1024), mebibytes, gibibytes,
+    tebibytes. If "**\--si**" appears before this option, suffixes will
+    denote kilobytes (\*1000), megabytes, and so on instead.
+
+    If *SIZE* starts with "**@**", the size of file whose name follows
+    the @ will be used; if that is a directory, the size of all files
+    under it will be used, like "**du \--apparent-size -b**".
+
+**-g, \--gauge**
+
+:   If the progress bar is shown but the size is not known, then instead
+    of moving the bar left and right to show progress, show the current
+    transfer rate as a percentage of the maximum rate seen so far.
+
+**-l, \--line-mode**
+
+:   Instead of counting bytes, count lines (newline characters). The
+    progress bar will only move when a new line is found, and the value
+    passed to "**\--size**" will be interpreted as a line count.
+
+    If this option is used without "**\--size**", the \"total size\" (in
+    this case, total line count) is calculated by reading through all
+    input files once before transfer starts. If any inputs are pipes or
+    non-regular files, or are unreadable, the total size will not be
+    calculated.
+
+**-0, \--null**
+
+:   Count lines as terminated with a null byte instead of with a
+    newline. This option implies "**\--line-mode**".
+
+**-i SEC, \--interval SEC**
+
+:   Wait *SEC* seconds between updates. The default is to update every
+    second. The value of *SEC* can be a decimal such as "0.1".
+
+**-m SEC, \--average-rate-window SEC**
+
+:   Compute current average rate over a *SEC* seconds window for average
+    rate and ETA calculations. The default is 30 seconds. The value must
+    be an integer.
+
+**-w WIDTH, \--width WIDTH**
+
+:   Assume the terminal is *WIDTH* columns wide, instead of
+    autodetecting the width (or assuming 80 if detection fails). If this
+    option is used, the output width will not be adjusted if the width
+    of the terminal changes while the transfer is running.
+
+**-H HEIGHT, \--height HEIGHT**
+
+:   Assume the terminal is *HEIGHT* rows high, instead of autodetecting
+    the height (or assuming 25 if detection fails). If this option is
+    used, the output height will not be adjusted if the height of the
+    terminal changes while the transfer is running.
+
+**-N NAME, \--name NAME**
+
+:   Prefix the output information with *NAME*. Often used with
+    "**\--cursor**" to identify each progress bar in a pipeline
+    containing more than one **pv**.
+
+**-u STYLE, \--bar-style STYLE**
+
+:   Change the default progress bar style shown by "**\--progress**", or
+    by the "**\--format**" sequences "**%{progress}**" or
+    "**%{progress-bar-only}**", to *STYLE*. The *STYLE* can be one of
+    **plain** (the default), **block**, **granular**, or **shaded**.
+    These styles are described in the **FORMATTING** section below.
+
+**-x SPEC, \--extra-display SPEC**
+
+:   As well as displaying progress to the terminal, also write it to
+    *SPEC*. The *SPEC* must start with a comma-separated list of
+    destinations, and can optionally be followed by a colon and a format
+    string. The destinations can be **windowtitle** or **window** for
+    the xterm window title, and **processtitle**, **proctitle**,
+    **process**, or **proc** for the process title displayed by
+    **ps**(1). If a format string is not supplied, the same format is
+    used as for the terminal. For example,
+    "**-x \'window,process:%t %b %r\'**" will show the elapsed time,
+    bytes transferred, and rate, in both the window title and the
+    process title.
+
+**-v, \--stats**
+
+:   At the end of the transfer, write an additional line showing the
+    transfer rate minimum, mean, maximum, and standard deviation. The
+    values are always in bytes per second (or bits, with "**\--bits**").
+
+**-f, \--force**
+
+:   Force output. Normally, **pv** will not output any visual display if
+    standard error is not a terminal. This option forces it to do so.
+
+**-c, \--cursor**
+
+:   Use cursor positioning escape sequences to move to the initial
+    terminal row when updating the display, instead of only using
+    carriage returns. This allows multiple **pv** instances to show
+    progress on the same terminal together.
+
+    For example:
+
+        pv --cursor --name input file.gz | gzip -d | pv --cursor --name output > file
+
+    As the example shows, this is often used with "**\--name**".
+
+## Data transfer modifiers
+
+**-o FILE, \--output FILE**
+
+:   Write data to *FILE* instead of standard output. If the file already
+    exists, it will be truncated.
+
+**-L RATE, \--rate-limit RATE**
+
+:   Limit the transfer to a maximum of *RATE* bytes per second. The same
+    suffixes as "**\--size**" can be used. Decimal values are allowed.
+    Specifying 0 will turn off rate limiting, which is useful with
+    "**\--remote**".
+
+**-B BYTES, \--buffer-size BYTES**
+
+:   Use a transfer buffer size of *BYTES* bytes. The same suffixes as
+    "**\--size**" can be used. The default buffer size is the block size
+    of the input file\'s filesystem multiplied by 32 (512KiB max), or
+    400KiB if the block size cannot be determined. This can be useful on
+    platforms like macOS with pipelines that perform better with
+    specific buffer sizes such as 1024. Implies "**\--no-splice**".
+
+**-C, \--no-splice**
+
+:   Prevent the use of **splice**(2) and **copy_file_range**(2), which
+    are normally used on systems that support it to improve efficiency
+    by eliminating the need for a transfer buffer.
+
+    In the default case that **splice**(2) or **copy_file_range**(2) are
+    used, the lack of a transfer buffer prevents "**\--buffer-percent**"
+    and "**\--last-written**" from working and makes
+    "**\--buffer-size**" redundant, so using any of those options
+    automatically switches on "**\--no-splice**".
+
+    Sparse files cannot be written with **splice**(2) or
+    **copy_file_range**(2), so using "**\--sparse**" automatically
+    switches on "**\--no-splice**".
+
+    Switching on "**\--no-splice**" results in a small loss of transfer
+    efficiency. It has no effect on systems where **splice**(2) and
+    **copy_file_range**(2) are unavailable.
+
+**-J BYTES, \--pipe-buffer-size BYTES**
+
+:   Attempt to set the size of the output pipe buffer, and the
+    intermediate input pipe buffer if one is needed, to *BYTES* bytes.
+    This will silently do nothing if the requested size cannot be
+    achieved. If this option is not specified, and both the output and
+    the first input are pipes, then the output pipe buffer size will
+    automatically be increased to match the input pipe buffer, if it was
+    smaller.
+
+**-E, \--skip-errors**
+
+:   Ignore read errors by attempting to skip past the offending
+    sections. The corresponding parts of the output will be null bytes.
+    At first only a few bytes will be skipped, but if there are many
+    errors in a row then the skips will move up to chunks of 512. This
+    is intended to be similar to "*dd conv=sync,noerror*".
+
+    Specify "**\--skip-errors**" twice to only report a read error once
+    per file, instead of reporting each byte range skipped.
+
+**-Z BYTES, \--error-skip-block BYTES**
+
+:   When ignoring read errors with "**\--skip-errors**", instead of
+    trying to adaptively skip by reading small amounts and skipping
+    progressively larger sections until a read succeeds, move to the
+    next file block of *BYTES* bytes as soon as an error occurs. There
+    may still be some shorter skips where the block being skipped
+    coincides with the end of the transfer buffer. The same suffixes as
+    "**\--size**" can be used.
+
+    This option can only be used with "**\--skip-errors**" and is
+    intended for use when reading from a block device, such as
+    "**\--skip-errors \--error-skip-block 4K**" to skip in 4 kibibyte
+    blocks. This will speed up reads from faulty media, at the expense
+    of potentially losing more data.
+
+**-S, \--stop-at-size**
+
+:   If a size was specified with "**\--size**", stop transferring data
+    once that many bytes have been written, instead of continuing to the
+    end of input.
+
+**-Y, \--sync**
+
+:   After every write operation, synchronise the buffer caches to disk
+    with **sync**(2), or **fdatasync**(2) if possible. This has no
+    effect when the output is a pipe. Using "**\--sync**" may improve
+    the accuracy of the progress bar when writing to a slow disk.
+
+**-K, \--direct-io**
+
+:   Set the **O_DIRECT** flag on all inputs and outputs, if it is
+    available. This will minimise the effect of caches, at the cost of
+    performance. Due to memory alignment requirements, it also may cause
+    read or write failures with an error of "Invalid argument",
+    especially if reading and writing files across a variety of
+    filesystems in a single **pv** call. Use this option with caution.
+
+**-O, \--sparse**
+
+:   When writing null bytes, try to seek, producing a sparse output
+    file. Implies "**\--no-splice**". On filesystems without sparse file
+    support, or when the output is not seekable, this option will have
+    no effect other than to turn on "**\--no-splice**".
+
+**-X, \--discard**
+
+:   Instead of transferring input data to standard output, discard it.
+    This is equivalent to redirecting standard output to */dev/null*,
+    except that **write**(2) is never called.
+
+**-U FILE, \--store-and-forward FILE**
+
+:   Instead of passing data through immediately, do it in two stages -
+    first read all input and write it to *FILE*, and then once the input
+    is exhausted, read all of *FILE* and write it to the output. *FILE*
+    remains in place afterwards, unless it is "**-**", in which case
+    **pv** creates a temporary file for this purpose, and automatically
+    removes it afterwards.
+
+    A common use for this is this where one part of a pipeline generates
+    data quickly but of unknown size, and the next part processes it
+    slowly. With "*quick* **\| pv -U - \|** *slow*", a progress bar is
+    displayed with unknown size for the *quick* part, then a second is
+    shown with a known size and ETA for the *slow* part.
+
+## Alternative operating modes
+
+**-d**, **\--watchfd** *PID*\[:*FD*\]\|=*NAME*\|@*LISTFILE*\...
+
+:   Instead of transferring data, watch file descriptor *FD* of process
+    *PID*, and show its progress. Other data transfer modifiers - and
+    remote control - may not be used with this option.
+
+    If a *PID* is specified without an *FD*, then that process will be
+    watched, and all regular files and block devices it opens will be
+    shown with a progress bar.
+
+    If a *NAME* is specified, prefixed with \"=\", then processes with
+    that name will be found with **pgrep**(1), and as watched described
+    above.
+
+    If a *LISTFILE* is specified, prefixed with \"@\", the lines in that
+    file will be used as additional arguments.
+
+    All remaining non-option arguments will also be treated as
+    additional arguments.
+
+    The **pv** process will exit when all *FD*s have either changed to a
+    different file, changed read/write mode, or have closed, and all
+    *PID*s (without a specific *FD*) have exited.
+
+**-R PID, \--remote PID**
+
+:   Remotely control another instance of **pv** with process ID *PID*,
+    making it act as though it had been given this instance\'s command
+    line. For example, if "**pv \--rate-limit 123K**" is running with
+    process ID 9876, then running
+    "**pv \--remote 9876 \--rate-limit 321K**" will cause process 9876
+    to start using a rate limit of 321KiB instead of 123KiB. Note that
+    some options cannot be changed while running, such as
+    "**\--cursor**", "**\--line-mode**", "**\--force**",
+    "**\--delay-start**", "**\--skip-errors**", and
+    "**\--stop-at-size**".
+
+**-Q PID, \--query PID**
+
+:   Display the transfer progress of another instance of **pv** with
+    process ID *PID*, owned by the same user.
+
+    Some output modifiers can only be used while querying another
+    process if they match those of that process - such as
+    "**\--line-mode**", "**\--null**", and "**\--average-rate-window**".
+    Data transfer modifiers will have no effect.
+
+**-M** *SIDE*, **\--monitor** *SIDE*
+
+:   Run the command specified by the remaining arguments, and monitor
+    its standard input, its standard output, or both, depending on
+    whether *SIDE* is "**in**", "**out**", or "**both**". Use "**\--**"
+    after all of the **pv** options to keep the monitored command\'s
+    options separate.
+
+    With a *SIDE* of "**both**", two progress bars will be shown. All of
+    **pv**\'s display switches, output modifiers, and data transfer
+    modifiers will apply to both sides.
+
+    For example, "**pv \--cursor \--monitor both \-- gzip -9**" is
+    equivalent to "**pv \--cursor \| gzip -9 \| pv \--cursor**", except
+    that the latter can\'t show the input:output ratio.
+
+    The "**\--format**" and "**\--name**" options may be specified
+    twice, in which case the first one applies to the input side and the
+    second applies to the output side. If no "**\--format**" options are
+    specified, the default format based on the other display switches is
+    used as normal, except that the ratio is added to the output side
+    when *SIDE* is "**both**".
+
+    The values "**0**", "**1**", and "**2**" may be used as synonyms for
+    "**in**", "**out**", and "**both**".
+
+    This option cannot be used with "**\--store-and-forward".**
+
+## Other options
+
+**-P FILE, \--pidfile FILE**
+
+:   Save the process ID of **pv** in *FILE*. The file will be replaced
+    if it already exists, and will be removed when **pv** exits. While
+    **pv** is running, *FILE* will contain a single number - the process
+    ID of **pv** - followed by a newline.
+
+**-h, \--help**
+
+:   Print a usage message on standard output and exit successfully.
+
+**-V, \--version**
+
+:   Print version information on standard output and exit successfully.
+
+# FORMATTING
+
+Format strings used by "**\--format**" and "**\--extra-display**" can
+contain the following sequences:
+
+**%p**, **%{progress}**
+
+:   Progress bar (suffixed with a percentage if the size is known).
+    Equivalent to "**\--progress**". Expands to fill the remaining space
+    unless prefixed by a number to set the width, such as "**%20p**" or
+    "**%20{progress}**".
+
+**%{progress-bar-only}**
+
+:   Progress bar, without any sides, and without any percentage
+    displayed afterwards. Expands to fill the remaining space unless
+    prefixed by a number.
+
+**%{progress-amount-only}**
+
+:   The percentage completion (or maximum rate, with "**\--gauge**" when
+    the size is unknown).
+
+**%{bar-plain}**
+
+:   Progress bar in the standard plain format, without any sides, and
+    without any percentage displayed afterwards. Expands to fill the
+    remaining space unless prefixed by a number.
+
+**%{bar-block}**
+
+:   Progress bar using Unicode full blocks, without any sides, and
+    without any percentage displayed afterwards. Expands to fill the
+    remaining space unless prefixed by a number. If UTF-8 output is not
+    available, the plain format is used.
+
+**%{bar-granular}**
+
+:   Progress bar using Unicode full blocks, and 1/8th blocks for partial
+    fills, providing a more granular display. Like the other "%{bar}"
+    strings this shows the bar without any sides, and without any
+    percentage displayed afterwards, and expands to fill the remaining
+    space unless prefixed by a number. If UTF-8 output is not available,
+    the plain format is used.
+
+**%{bar-shaded}**
+
+:   Progress bar using Unicode full blocks and shade characters - dark
+    and medium shade are used for partial fills, and the light shade is
+    used for the background. Like the other "%{bar}" strings this shows
+    the bar without any sides, and without any percentage displayed
+    afterwards, and expands to fill the remaining space unless prefixed
+    by a number. If UTF-8 output is not available, the plain format is
+    used.
+
+**%t**, **%{timer}**
+
+:   Elapsed time. Equivalent to "**\--timer**".
+
+**%e**, **%{eta}**
+
+:   ETA as time remaining. Equivalent to "**\--eta**".
+
+**%I**, **%{fineta}**
+
+:   ETA as local time at which the transfer will finish. Equivalent to
+    "**\--fineta**".
+
+**%r**, **%{rate}**
+
+:   Current data transfer rate. Equivalent to "**\--rate**".
+
+**%a**, **%{average-rate}**
+
+:   Average data transfer rate. Equivalent to "**\--average-rate**".
+
+**%b**, **%{bytes}**, **%{transferred}**
+
+:   Bytes transferred so far (or lines if "**\--line-mode**" was
+    specified). Equivalent to "**\--bytes**". If "**\--bits**" was
+    specified, "**%b**" shows the bits transferred so far, not bytes.
+
+**%{ratio}**
+
+:   Show the ratio of bytes transferred by the other side to the bytes
+    transferred by this side, in "**\--monitor both**" mode.
+
+**%T**, **%{buffer-percent}**
+
+:   Percentage of the transfer buffer in use. Equivalent to
+    "**\--buffer-percent**", but using it does not turn on
+    "**\--no-splice**".
+
+    If the transfer is using **splice**(2), displays "{\-\-\--}"; if the
+    transfer is using **splice**(2) via an intermediate input pipe,
+    displays "{-\|\|-}"; and if the transfer is using
+    **copy_file_range**(2), displays "{\-\--\>}".
+
+**%nA**, **%n{last-written}**
+
+:   Show the last *n* bytes written (for example, "**%16A**" shows the
+    last 16 bytes). Shows only dots if the transfer is using
+    **splice**(2) or **copy_file_range**(2), since these transfer modes
+    do not use the buffer.
+
+**%nL**, **%n{previous-line}**
+
+:   Show the first *n* bytes of the most recently written line (for
+    example, "**%40L**" shows the first 40 bytes). If no *n* is given,
+    then this expands to fill the available space. Shows only spaces if
+    the transfer is using **splice**(2) or **copy_file_range**(2).
+
+**%N**, **%{name}**
+
+:   Show the name prefix given by "**\--name**". Padded to 9 characters
+    with spaces, and suffixed with ":".
+
+**%{sgr:colour,\...}**
+
+:   Emit ECMA-48 SGR (Select Graphic Rendition) codes if the terminal
+    supports colours, where *colour,\...* is a comma-separated list of
+    any of the keywords below, or the numeric values from
+    **console_codes**(4). If colour support is not available, nothing is
+    emitted.
+
+    Supported keywords are: **reset** or **none**, **black**, **red**,
+    **green**, **brown** or **yellow**, **blue**, **magenta**, **cyan**,
+    **white**, **fg-black**, **fg-red**, **fg-green**, **fg-brown** or
+    **fg-yellow**, **fg-blue**, **fg-magenta**, **fg-cyan**,
+    **fg-white**, **fg-default**, **bg-black**, **bg-red**,
+    **bg-green**, **bg-brown** or **bg-yellow**, **bg-blue**,
+    **bg-magenta**, **bg-cyan**, **bg-white**, **bg-default**, **bold**,
+    **dim**, **italic**, **underscore** or **underline**, **blink**,
+    **reverse**, **no-bold** or **no-dim**, **no-italic**,
+    **no-underscore** or **no-underline**, **no-blink**, **no-reverse**.
+
+    With colours, the optional \"fg-\" prefix indicates foreground; a
+    prefix of \"bg-\" indicates background.
+
+    For example, "**%{sgr:green,bold}TEXT%{sgr:reset}**" will make
+    *TEXT* bold green on supported terminals.
+
+**%%**
+
+:   A single "%".
+
+Any other contents are reproduced in the progress display as-is.
+
+The format string equivalent of the default display switches is
+"**%b %t %r %p %e**".
+
+# EXAMPLES
+
+Some suggested common switch combinations:
+
+**pv -ptebar**
+
+:   Show a progress bar, elapsed time, estimated completion time, byte
+    counter, average rate, and current rate.
+
+**pv -betlap**
+
+:   Show a progress bar, elapsed time, estimated completion time, line
+    counter, and average rate, counting lines instead of bytes.
+
+**pv -btrpg**
+
+:   Show the amount transferred, elapsed time, current rate, and a gauge
+    showing the current rate as a percentage of the maximum rate seen -
+    useful in a pipeline where the total size is unknown. (If the size
+    *is* known, these options will show the percentage completion
+    instead of the rate gauge).
+
+**pv -t**
+
+:   Show only the elapsed time - useful as a simple timer, such as
+    "**sleep 10m \| pv -t**".
+
+**pv -pterb**
+
+:   The default behaviour: progress bar, elapsed time, estimated
+    completion time, current rate, and byte counter.
+
+On macOS, it may be useful to specify "**\--buffer-size 1024**" in a
+pipeline, as this may improve performance.
+
+To watch how quickly a file is transferred using **nc**(1):
+
+    pv file | nc -w 1 somewhere.com 3000
+
+A similar example, transferring a file from another process and passing
+the expected size to **pv**:
+
+    cat file | pv --size 12345 | nc -w 1 somewhere.com 3000
+
+To watch the progress of creating a tar.gz archive:
+
+    tar cf - directory/ \
+    | pv --size $(du -sb directory/ | awk '{print $1}') \
+    | gzip -9 \
+    > out.tar.gz
+
+An alternative way of doing the same thing:
+
+    tar cf - directory/ \
+    | pv --size @directory/ \
+    | gzip -9 \
+    > out.tar.gz
+
+Taking an image of a disk, skipping errors:
+
+    pv -EE /dev/your/disk/device > disk-image.img
+
+Writing an image back to a disk:
+
+    pv disk-image.img > /dev/your/disk/device
+
+Zeroing a disk:
+
+    pv < /dev/zero > /dev/your/disk/device
+
+Note that if the input size cannot be calculated, and the output is a
+block device, then the size of the block device will be used and **pv**
+will automatically stop at that size as if "**\--stop-at-size**" had
+been given.
+
+(Linux and macOS only): Watching file descriptor 3 opened by another
+process 1234:
+
+    pv --watchfd 1234:3
+
+(Linux and macOS only): Watching all file descriptors used by process
+1234:
+
+    pv --watchfd 1234
+
+Rate-limiting the transfer between two processes in a pipeline, with no
+display:
+
+    producer | pv --quiet --rate-limit 1M | consumer
+
+Sending logs to a processing script, showing the most recent line as
+part of the progress display:
+
+    pv --no-splice --format '%a %p : %L' big.log | processing-script
+
+Showing progress as lines of JSON data:
+
+    pv --numeric --format '{"elapsed":%t,"bytes":%b,"rate":%r,"percentage":%{progress-amount-only}}' big.log | processing-script
+
+# EXIT STATUS
+
+An exit status of 1 indicates a problem with the "**\--remote**",
+"**\--query**", "**\--pidfile**", or "**\--monitor**" options.
+
+Any other exit status is a bitmask of the following:
+
+ **2**
+
+:   One or more files could not be accessed, **stat**(2)ed, or opened.
+
+ **4**
+
+:   An input file was the same as the output file.
+
+ **8**
+
+:   Internal error with closing a file or moving to the next file.
+
+ **16**
+
+:   There was an error while transferring data from one or more input
+    files.
+
+ **32**
+
+:   A signal was caught that caused an early exit.
+
+ **64**
+
+:   Memory allocation failed.
+
+A zero exit status indicates no problems.
+
+# ENVIRONMENT
+
+The following environment variables may affect **pv**:
+
+**HOME**
+
+:   The current user\'s home directory. This may be used by
+    "**\--remote**" and "**\--query**" to exchange messages between
+    **pv** instances: if the */run/user/UID/* directory does not exist
+    (where *UID* is the current user ID), then *\$HOME/.pv/* will be
+    used instead.
+
+**TMPDIR**, **TMP**
+
+:   The directory to create per-tty lock files for the terminal when
+    using "**\--cursor**". If **TMPDIR** is set to a non-empty value, it
+    is the directory under which lock files are created. Otherwise,
+    **TMP** is used. If neither are set, then */tmp* is used.
+
+# NOTES
+
+In some versions of **bash**(1) and **zsh**(1), the construct
+"**\<(pv filename)**" will not output any progress to the terminal when
+run from an interactive shell, due to the subprocess being run in a
+separate process group from the one that owns the terminal. In these
+cases, use "**\--force**".
+
+If **pv** is used in a pipeline in **zsh** version 5.8, and the last
+command in the pipeline is based on shell builtins, **zsh** takes
+control of the terminal away from **pv**, preventing progress from being
+displayed. For example, this will produce no progress bar:
+
+    pv InputFile | { while read -r line; do sleep 0.1; done; }
+
+To work around this, put the last commands of the pipeline in normal
+brackets to force the use of a subshell:
+
+    pv InputFile | ( while read -r line; do sleep 0.1; done; )
+
+Refer to [issue #105](https://codeberg.org/ivarch/pv/issues/105) for
+full details.
+
+The "**\--remote**" and "**\--query**" options require that either
+*/run/user/\<uid\>/* or *\$HOME/* can be written to, for inter-process
+communication.
+
+The "**\--size**" option has no effect if used with
+"**\--watchfd** *PID*" to watch all file descriptors of a process, but
+will work with "**\--watchfd** *PID*:*FD*" to watch a single file
+descriptor.
+
+If the input size cannot be calculated, and the output is a block
+device, then **pv** will read the output device\'s size, use that as if
+it had been passed to "**\--size**", and activate "**\--stop-at-size**".
+
+The "**%nA**" and "**%nL**" format sequences may not be effective with
+small input files, and "**%nL**" may be a few lines out due to buffering
+within the pipeline itself.
+
+Numbers passed to "**\--size**", "**\--buffer-size**",
+"**\--pipe-buffer-size**", and "**\--error-skip-block**" may all be
+expressed as decimals if followed by a suffix, so for example
+"*\--size 1.5G*" is equivalent to "*\--size 1536M*".
+
+Numbers passed to "**\--rate-limit**" may be expressed as decimals with
+or without a suffix.
+
+Numbers passed to "**\--interval**" and "**\--delay-start**" may be
+integers or decimals, but may not have a suffix.
+
+Numbers passed to "**\--last-written**", "**\--width**",
+"**\--height**", "**\--average-rate-window**", "**\--remote**", and
+"**\--query**" must be integers with no suffix.
+
+When "**\--sparse**" is in effect and output is being written to a file,
+that file may look like it has stopped growing if inspected with
+**ls**(1) while null bytes are being written, even though **pv** still
+reports progress. This is because of the way sparse output is achieved,
+and the file will be the correct size when the transfer ends.
