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.
- Single shot - this instructs the program to only return one
- 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.
- 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.
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.
