NAME
     pgrep, pkill -- find or signal processes by name

SYNOPSIS
     pgrep [-flnovx] [-d delim]	[-G gid] [-g pgrp] [-P ppid] [-s sid] [-t tty]
	   [-U uid] [-u	euid] [pattern ...]
     pkill [-signal] [-fnovx] [-G gid] [-g pgrp] [-P ppid] [-s sid] [-t	tty]
	   [-U uid] [-u	euid] [pattern ...]

DESCRIPTION
     The pgrep command searches	the process table on the running system	and
     prints the	process	IDs of all processes that match	the criteria given on
     the command line.

     The pkill command searches	the process table on the running system	and
     signals all processes that	match the criteria given on the	command	line.

     The following options are available:

     -d	delim
	     Specify a delimiter to be printed between each process ID.	 The
	     default is	a newline.  This option	can only be used with the
	     pgrep command.

     -f	     Match against full	argument lists.	 The default is	to match
	     against process names.

     -G	gid  Restrict matches to processes with	a real group ID	in the comma-
	     separated list gid.

     -g	pgrp
	     Restrict matches to processes with	a process group	ID in the
	     comma-separated list pgrp.	 The value zero	is taken to mean the
	     process group ID of the running pgrep or pkill command.

     -l	     Long output.  Print the process name in addition to the process
	     ID	for each matching process.  If used in conjunction with	-f,
	     print the process ID and the full argument	list for each matching
	     process.  This option can only be used with the pgrep command.

     -n	     Match only	the most recently created (newest) process, if any.
	     Cannot be used in conjunction with	-o.

     -o	     Match only	the least recently created (oldest) process, if	any.
	     Cannot be used in conjunction with	-n.

     -P	ppid
	     Restrict matches to processes with	a parent process ID in the
	     comma-separated list ppid.

     -s	sid  Restrict matches to processes with	a session ID in	the comma-sep-
	     arated list sid.  The value zero is taken to mean the session ID
	     of	the running pgrep or pkill command.

     -t	tty  Restrict matches to processes associated with a terminal in the
	     comma-separated list tty.	Terminal names may be of the form
	     `ttyxx' or	the shortened form `xx'.  A single dash	(`-') matches
	     processes not associated with a terminal.

     -U	uid  Restrict matches to processes with	a real user ID in the comma-
	     separated list uid.

     -u	euid
	     Restrict matches to processes with	an effective user ID in	the
	     comma-separated list euid.

     -v	     Reverse the sense of the matching;	display	or signal processes
	     that do not match the given criteria.

     -x	     Require an	exact match of the process name, or argument list if
	     -f	is given.  The default is to match any substring.

     -signal
	     A non-negative decimal number or symbolic signal name specifying
	     the signal	to be sent instead of the default TERM.	 This option
	     is	valid only when	given as the first argument to pkill.

     If	any pattern operands are specified, they are used as regular expres-
     sions to match the	command	name or, if -f is specified, the full argument
     list of each process.  However, presently OpenBSD will only keep track of
     the first 16 characters of	the command name for each process.  Attempts
     to	match any characters after the first 16	of a command name will
     silently fail.

     Note that a running pgrep or pkill	process	will never consider itself or
     system processes (kernel threads) as a potential match.

EXIT STATUS
     The pgrep and pkill utilities exit	with one of the	following values:

	   0	   One or more processes were matched.
	   1	   No processes	were matched.
	   2	   Invalid options were	specified on the command line.
	   3	   An internal error occurred.

HISTORY
     pkill and pgrep first appeared in OpenBSD 3.5.  They are modelled after
     utilities of the same name	that appeared in Sun Solaris 7.
