NAME
pidof -- find the process ID of a running program.
SYNOPSIS
pidof
[-s]
[-c]
[-x]
[-oomitpid]
[-oomitpid..]
program
[program..]
DESCRIPTION
Pidof
finds the process id's (pids) of the named programs. It prints those
id's on the standard output. This program is on some systems used in
run-level change scripts, especially when the system has a
System-V like rc structure. In that case these scripts are
located in /etc/rc?.d, where ? is the runlevel. If the system has
a
start-stop-daemon
(8) program that should be used instead.
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 does not make sense 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
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.
NOTES
pidof is simply a (symbolic) link to the killall5 program,
which should also be located in /sbin.
When pidof is invoked with a full pathname to the program it
should find the pid of, it is reasonably safe. Otherwise it is possible
that it returns pids of running programs that happen to have the same name
as the program you're after but are actually other programs.
