vovps

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.

Examples

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
}
