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.
 

SEE ALSO

shutdown(8), init(8), halt(8), reboot(8)  

Important: Use the man command (% man) to see how a command is used on your particular computer.
