PIDOF(8)	      Linux System Administrator's Manual	      PIDOF(8)

NAME
       pidof -- find the process ID of a running program.

SYNOPSIS
       pidof [-s] [-c] [-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.

       -c     Only return process ids that are	running	 with  the  same  root
	      directory.   This	 option is ignored for non-root users, as they
	      will be unable to check the current root directory of  processes
	      they do not own.

       -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.
