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.
A manual page is included in this distribution. See "man ./doc/quickref.1",
or "man pv" after installation.
If this is not a packaged release, first run "./generate.sh".
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.
See the file "doc/INSTALL" for more about the configure script.
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.
