2
6 pidof -- find the process ID of a running program.
7
9 pidof [-s] [-c] [-x] [-o omitpid[,omitpid..]] [-o omitpid[,omit‐
10 pid..]..] [-S separator] program [program..]
11
13 Pidof finds the process id's (pids) of the named programs. It prints
14 those id's on the standard output.
15
17 -s Single shot - this instructs the program to only return one pid.
18 -c Only return process ids that are running with the same root
20 directory. This option is ignored for non-root users, as they
21 will be unable to check the current root directory of processes
22 they do not own.
23 -x Scripts too - this causes the program to also return process
25 id's of shells running the named scripts.
26 -w Show also processes that do not have visible command line (e.g.
28 kernel worker threads).
29 -o omitpid
31 Tells pidof to omit processes with that process id. The special
32 pid %PPID can be used to name the parent process of the pidof
33 program, in other words the calling shell or shell script.
34 -S separator
36 Use separator as a separator put between pids. Used only when
37 more than one pids are printed for the program. The -d option
38 is an alias for this option for sysvinit pidof compatibility.
39
41 0 At least one program was found with the requested name.
42 1 No program was found with the requested name.
44
47 When using the -x option, pidof only has a simple method for detecting
48 scripts and will miss scripts that, for example, use env. This limita‐
49 tion is due to how the scripts look in the proc filesystem.

53 pgrep(1), pkill(1)
