Package: moreutils
Version: 0.62-1
Severity: wishlist
Tags: upstream
I'd like to propose a new program be added to more utils, named
`waitpid`, which does a similar task than the `wait` shell builtin,
except it's not restricted to sub-processes. My dumb implementation is
a simple shell script that waits on the PID like so:
#!/bin/sh
while [ -e /proc/$1 ]; do
sleep 1
done
We could add all sorts of bells and whistles on top of that
(e.g. customize the loop time, rewrite in Perl or Python) but I think
that would be overthinking it.
I'm using the above regularly now in combination to `undistract-me` to
notify me of long-running tasks on remote servers. If you don't have
`undistract-me` installed, this would be the equivalent:
ssh remote waitpid 1234 ; notify-send 'process finished'
I'd be happy to work on a patch to moreutils to include this,
including a simple manpage.
Let me know if it makes sense.
