PIDOF(1) User Commands PIDOF(1)
pidof -- find the process ID of a running program
pidof [-s] [-c] [-q] [-w] [-x] [-o omitpid[,omitpid...]...] [-S
separator] program [program...]
Pidof finds the process id's (pids) of the named programs. It
prints those id's on the standard output.
-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.
-q Quiet mode, suppress any output and only sets the exit
status accordingly.
-w Show also processes that do not have visible command line
(e.g. kernel worker threads).
-x Scripts too - this causes the program to also return
process id's of shells running the named scripts.
-o omitpid
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.
-S separator
Use separator as a separator put between pids. Used only
when more than one pids are printed for the program. The
-d option is an alias for this option for sysvinit pidof
compatibility.
0 At least one program was found with the requested name.
1 No program was found with the requested name.
When using the -x option, pidof only has a simple method for
detecting scripts and will miss scripts that, for example, use
env. This limitation is due to how the scripts look in the proc
filesystem.
