RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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):
psacct-6.6.1-9.el7.x86_64

Steps to Reproduce:
1. lastcomm --pid


Actual results:
<snip>
[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 ~]# 
</snip>

Expected results:
<snip>
[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.

Thanks,
Jaromir.
