PIDOF !!!PIDOF NAME SYNOPSIS DESCRIPTION OPTIONS NOTES SEE ALSO AUTHOR ---- !!NAME pidof -- find the process ID of a running program. !!SYNOPSIS __pidof__ [[__-s__] [[__-x__] [[__-o__ ''omitpid''] [[__-o__ ''omitpid..''] __program__ [[__program..__] !!DESCRIPTION __Pidof__ finds the process id's (pids) of the named programs. It prints those id's on the standard output. This program is on some systems used in run-level change scripts, especially when the system has a ''System-V'' like ''rc'' structure. In that case these scripts are located in /etc/rc?.d, where ? is the runlevel. If the system has a __start-stop-daemon__ (8) program that should be used instead. !!OPTIONS -s Single shot - this instructs the program to only return one ''pid''. -x Scripts too - this causes the program to also return process id's of shells running the named scripts. -o Tells ''pidof'' to omit processes with that process id. The special pid __%PPID__ can be used to name the parent process of the ''pidof'' program, in other words the calling shell or shell script. !!NOTES ''pidof'' is simply a (symbolic) link to the ''killall5'' program, which should also be located in ''/sbin''. When ''pidof'' is invoked with a full pathname to the program it should find the pid of, it is reasonably safe. Otherwise it is possible that it returns pids of running programs that happen to have the same name as the program you're after but are actually other programs. !!SEE ALSO shutdown(8), init(8), halt(8), reboot(8) !!AUTHOR Miquel van Smoorenburg, miquels@cistron.nl ----
