pidof — find the process ID of a running program.
Synopsis
pidof [-s] [-c] [-x] [-o omitpid[,omitpid..]] [-o omitpid[,omitpid..]..] program [program..]Description
Pidof finds the process id’s (pids) of the named programs. It prints those id’s on the standard output.Options
- -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.
Exit Status
