pidof -- find the process ID of a running program.
pidof [-s] [-c] [-x] [-o omitpid] [-o omitpid..] program [program..]
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-stopdaemon (8) program that should be used instead.
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.
shutdown(8) , init(8) , halt(8) , reboot(8)
