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 no-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.
- -t
-
Shows all thread ids instead of pids.
- -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.
EXIT STATUS
- 0
-
At least one program was found with the requested name.
- 1
-
No program was found with the requested name.
BUGS
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.
