PIDOF(1) User Commands PIDOF(1)
pidof -- find the process ID of a running program
pidof [-s] [-c] [-x] [-o omitpid[,omitpid...]] [-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.
-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.
