Description Frank Hirtz 2001-11-09 15:24:20 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.5) Gecko/20011012

Description of problem:
We need an option to ps to suppress the display of threads.  The manpage
suggests a -m option to show threads (suggesting an obvious -M to suppress
them?) but the version shipped with Red Hat Linux responds "ps: error:
Thread display not implemented".

This is coming up in a number of contexts and so is a relatively high priority.


This should be tied to the work that is already being done to have the
kernel export some information on threads (tgid) which should already be

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

How reproducible:

Steps to Reproduce:
1.ps -m

Actual Results:  ps: error: Thread display not implemented.

The "fix" leaves no way to display the complete list of pids (even if they are
just threads).   There should be an option to have the old behavior. -m doesn't
display them

On what system does -m not work?
It does work for me on e.g. RH 8.0.
