pidof
PIDOF(8) Linux System Administrator's Manual PIDOF(8)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 pro-
gram, 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.
