Description

bash completion for gdb fails, because ps does not support "o" option:

# gdb /lib/inet/ipmgmtd <TAB>ps: illegal option -- o
usage: ps [ -aceglnrSuUvwx ] [ -t term ] [ num ]

From Linux man page:

       o format
              Specify user-defined format.  Identical to -o and --format.

       -o format
              User-defined format.  format is a single argument in the form of a blank-separated or comma-separated list, which offers a way to specify
              individual output columns.  The recognized keywords are described in the STANDARD FORMAT SPECIFIERS section below.  Headers may be renamed
              (ps -o pid,ruser=RealUser -o comm=Command) as desired.  If all column headers are empty (ps -o pid= -o comm=) then the header line will
              not be output.  Column width will increase as needed for wide headers; this may be used to widen up columns such as WCHAN (ps -o pid,
              wchan=WIDE-WCHAN-COLUMN -o comm).  Explicit width control (ps opid,wchan:42,cmd) is offered too.  The behavior of ps -o pid=X,comm=Y
              varies with personality; output may be one column named "X,comm=Y" or two columns named "X" and "Y".  Use multiple -o options when in
              doubt.  Use the PS_FORMAT environment variable to specify a default as desired; DefSysV and DefBSD are macros that may be used to choose
              the default UNIX or BSD columns.
