NAME

6       pidof - find the process ID of a running program
7

SYNOPSIS

9       pidof  [-s] [-c] [-q] [-w] [-x] [-o omitpid[,omitpid...]...]  [-S sepa‐
10       rator] program [program...]
11

DESCRIPTION

13       Pidof finds the process id's (pids) of the named  programs.  It  prints
14       those id's on the standard output.
15

OPTIONS

17       -s     Single shot - this instructs the program to only return one pid.
18
19       -c     Only  return process ids that are running with the same root di‐
20              rectory.  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
24       -q     Quiet mode, suppress any output and only sets  the  exit  status
25              accordingly.
26
27       -w     Show  also processes that do not have visible command line (e.g.
28              kernel worker threads).
29
30       -x     Scripts too - this causes the program  to  also  return  process
31              id's of shells running the named scripts.
32
33       -o omitpid
34              Tells  pidof to omit processes with that process id. The special
35              pid %PPID can be used to name the parent process  of  the  pidof
36              program, in other words the calling shell or shell script.
37
38       -S separator
39              Use  separator  as  a separator put between pids. Used only when
40              more than one pids are printed for the program.  The  -d  option
41              is an alias for this option for sysvinit pidof compatibility.
42

EXIT STATUS

44       0      At least one program was found with the requested name.
45
46       1      No program was found with the requested name.
47
48

BUGS

50       When  using the -x option, pidof only has a simple method for detecting
51       scripts and will miss scripts that, for example, use env. This  limita‐
52       tion is due to how the scripts look in the proc filesystem.
