[Bug 2057944] Re: pidwait doesn't work. Instead behaves like pgrep

[Marian Sigler]

I know this isn't high priority, but it's really just a one-line change.
I don't know how but I've tracked down the "where", at least:

I think in pgrep.c
797:	if (strcmp (program_invocation_short_name, "pwait") == 0) {
must be updated to also check for pidwait, that should do it.

Workaround:

Run (once):
$ ln -s ../../bin/pidwait /usr/local/bin/pwait
Then use `pwait` instead of `pidwait`.

Title:
  pidwait doesn't work. Instead behaves like pgrep

Status in procps package in Ubuntu:
  Confirmed

Bug description:
  pidwait doesn't work at all.

  Seems like pidwait was renamed in an Ubuntu patch from upstream pwait
  - however the executable that is built acts as "pgrep" unless it's
  called as "pwait"; this check also needs to be updated with the
  executable name "pidwait".
