Hi,

somehow the ps tool seems not provide all known features anymore
at least elfutils-debuginfod test suite fails in our QA tests
with:

  [   93s] + ps -q 18200 -e -L -o '%p %c %a'
  [   93s] + grep groom
  [   93s] error: unknown user-defined format specifier "%p"

and if I use the example of the manual page I see

  noether:/ # ps -eo "%p %y %x %c"
  error: unknown user-defined format specifier "%p"

  Usage:
   ps [options]
 
   Try 'ps --help <simple|list|output|threads|misc|all>'
    or 'ps --help <s|l|o|t|m|a>'
   for additional help text.

  For more details see ps(1).

even if set personality

  noether:/ # env -i PS_PERSONALITY=aix ps -eo "%p %y %x %c"
  error: unknown user-defined format specifier "%p"

  Usage:
   ps [options]

   Try 'ps --help <simple|list|output|threads|misc|all>'
    or 'ps --help <s|l|o|t|m|a>'
   for additional help text.

  For more details see ps(1).
