[TynesideLUG] Pipe Viewer – A Unix Utility You Should Know About

[Ian Bruntlett]

Hi,

Saw some info about this command on the ubuntu-devel mailing list.:-

"The Ubuntu Server team is looking at several potential items to promote
to main, including cli admin tools that might have broad usefulness.
One of these we're on the fence about and would like broader input.

pv, 'Pipe Viewer' is a command line utility that essentially copies
stdin to stdout, and displays an animated progress bar.

Overview: https://catonmat.net/unix-utilities-pipe-viewer
Man page: https://linux.die.net/man/1/pv
LP page:  https://launchpad.net/ubuntu/+source/pv
"

It looks really useful.

Using it to time tar invocations is not really necessary because tar can be
told to output progress indicators. But the pv syntax looks a lot clearer
than the equivalent tar syntax. Horses for courses.

HTH,


Ian
