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. Hello Frank. The project has a bug tracker on savannah. https://savannah.gnu.org/bugs/?group=acct You could also try to contact Markus Gothe <nietzsche.se> directly. Created attachment 1249792 [details]

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] ...

[--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.
