vovps lists all processes, similar to the UNIX command ps. It is useful to understand the process hierarchy of Accelerator jobs, and sometimes to find which PIDs to kill in a shell.

The -c and -p options show the child processes and parent processes respectively of a given pid. The results are a Tcl list of pid, program name, and owner.

usage: vovps [-an] [-c pid] [-dgsSJj] [-p pid] [-mP]
   -a:         Print all processes, one per line, like a simple version of 'ps'
   -n:         Only print pids: must come before -c or -p
   -c:         Print the children of process <pid>. The printing is in Tcl
               format, but it is also easy to parse.
   -d:         Debug process info collection
   -g:         Include list of processes with same PGID to children
   -s:         Include list of processes with same SID to children
   -S:         Include state of process R,S,T,Z... 
   -J:         Include list of processes with same VOV_JOBID to children
   -j:         Like -a, but show the VOV_JOBID also and LM_PROJECT instead of
               command line
   -p:         Print the parents of process <pid>. Same format as for -c
   -m:         Print more detailed memory usage information (Linux).
   -P:         Use 'ps' program to scan the processes. This behavior can also
               be selected by setting the environment variable VOV_USE_PS.


Example 1:

% vovps -a | grep fire
31155 28981   1h06m    0    0    0.00    0.01 bkring    vovfire28981.cs
32381 32260  56m35s  977  219    6.45   70.33 bkring    firefox
Example 2: (the shell substitutes the current pid for '$$'):
% vovps -p $$
set parents(28756) {
   28754 "xterm" cadmgr
       1 "init" root
