Description Frank Hirtz 2015-08-19 21:08:08 UTC
Description of problem:

In rhel6, the lastcomm binary (part of the psacct package) included a patch which added a flag, --pid, which would print out the processes pid and ppid. 

It looks like that patch (psacct-6.3.2-ppid.patch) was dropped in rhel7. 

We've found it to be very useful and would like to see it restored in rhel7.

Version-Release number of selected component (if applicable):

Steps to Reproduce:
1. lastcomm --pid

Actual results:
[root@garabaldi ~]# lastcomm --pid
lastcomm: unrecognized option '--pid'
Usage: lastcomm [-hpV] [-f file] [command] ... [user] ... [terminal] ...
       [--forwards] [--file <file>] [--strict-match] [--print-controls]
       [--user <name>] [--tty <name>] [--command <name>] [--debug]
       [--show-paging] [--ahz <freq>] [--version] [--help]

The system's default process accounting file is /var/account/pacct.
[root@garabaldi ~]# 

Expected results:
[root@ivanova fmhirtz]# lastcomm --pid | head -5
lastcomm                root     pts/0      0.38 secs Wed Aug 19 17:06     3573     3551

Hello Frank.

The --pid switch was introduced by the previous component maintainer. Unfortunately the patch didn't get upstream for some reason. I could try to forward-port this and propagate upstream.

Let's see how that goes.

Hello Frank.

The project has a bug tracker on savannah.


You could also try to contact Markus Gothe <nietzsche.se> directly.
