Red Hat Bugzilla – Bug 85628
sort order for "ps fax" reversed from procps-2.0.7-25
Last modified: 2007-04-18 12:51:51 EDT
Description of problem: Under Psyche, the default sort order for the ps command is numeric ascending, by pid: $ ps fax PID TTY STAT TIME COMMAND 1 ? S 0:04 init 2 ? SW 0:01 [keventd] 3 ? SW 0:00 [kapmd] 4 ? SWN 0:00 [ksoftirqd_CPU0] 5 ? SW 0:05 [kswapd] 6 ? SW 0:00 [bdflush] 7 ? SW 0:00 [kupdated] 8 ? SW 0:00 [mdrecoveryd] 12 ? SW 0:01 [kjournald] 71 ? SW 0:00 [khubd] 231 ?

SW 0:01 [bdflush] 4 ? SWN 0:00 [ksoftirqd_CPU0] 3 ? SW 0:00 [kapmd] Phoebe's behavior doesn't agree with what the man page says. If this was a deliberate change (and not a bug), then I think it's dumb--ordering by descending pid is a great way to ensure that the processes that are left in my xterm after I run the ps command (e.g., bdflush, kjournald) are ones I *don't* care about. Version-Release number of selected component (if applicable): procps-2.0.11-3 (Phoebe) How reproducible: Run "ps fax" on Phoebe.
This should be fixed in 2.0.11-6
Are you certain? Because at approximately 2003-03-11T18:00-0500 I downloaded and installed: ftp://ftp.redhat.com/pub/redhat/linux/rawhide/i386/RedHat/RPMS/procps-2.0.11-6.i386.rpm $ rpm -q procps procps-2.0.11-6 But "ps fax" still returns a descending sort order, instead of ascending. Did I download the correct package?
Can you upgradet to the latest kernel to. There was some /proc changes in it. I get: # ps fax PID TTY STAT TIME COMMAND 1 ? S 0:04 init 2 ? SW 0:00 [keventd] 3 ? SW 0:00 [kapmd] 4 ?

Confirmed; the problem went away once I upgaded the kernel: $ rpm -q kernel procps kernel-2.4.20-2.54 procps-2.0.11-6 $ ps fax | head -10 PID TTY STAT TIME COMMAND 1 ? S 0:07 init 2 ?
