	29	.Dt KILLALL 1
	30	.Sh NAME
	31	.Nm killall
	32	.Nd kill processes by name
	33	.Sh SYNOPSIS
	34	.Nm
	35	.Op Fl delmsvz
	36	.Op Fl help
	37	.Op Fl u Ar user
	38	.Op Fl t Ar tty
	39	.Op Fl c Ar procname
	40	.Op Fl SIGNAL
	41	.Op Ar procname ...
	42	.Sh DESCRIPTION
	43	The
	44	.Nm
	45	utility kills processes selected by name, as opposed to the selection by pid
	46	as done by
	47	.Xr kill 1 .
	48	By default, it will send a
	49	.Dv TERM
	50	signal to all processes with a real UID identical to the
	51	caller of
	52	.Nm
	53	that match the name
	54	.Ar procname .
	55	The super-user is allowed to kill any process.
	56	.Pp
	57	The options are as follows:
	58	.Bl -tag -width 10n -offset indent
	59	.It Fl v
	60	Be more verbose about what will be done.
	61	.It Fl e
	62	Use the effective user ID instead of the (default) real user ID for matching
	63	processes specified with the
	64	.Fl u
	65	option.
	66	.It Fl help
	67	Give a help on the command usage and exit.
	68	.It Fl l
	69	List the names of the available signals and exit, like in
	70	.Xr kill 1 .
	71	.It Fl m
	72	Match the argument
	73	.Ar procname
	74	as a (case sensitive) regular expression against the names
	75	of processes found.
	76	CAUTION!
	77	This is dangerous, a single dot will match any process
	78	running under the real UID of the caller.
	79	.It Fl s
	80	Show only what would be done, but do not send any signal.
	81	.It Fl d
	82	Print detailed information about the processes matched,
	83	but do not send any signal.
	84	.It Fl SIGNAL
	85	Send a different signal instead of the default
	86	.Dv TERM .
	87	The signal may be specified either as a name
	88	(with or without a leading
	89	.Dv SIG ) ,
	90	or numerically.
	91	.It Fl u Ar user
	92	Limit potentially matching processes to those belonging to
	93	the specified
	94	.Ar user .
	95	.It Fl t Ar tty
	96	Limit potentially matching processes to those running on
	97	the specified
	98	.Ar tty .
	99	.It Fl c Ar procname
	100	When used with the
	101	.Fl u
	102	or
	103	.Fl t
	104	flags, limit potentially matching processes to those matching
	105	the specified
	106	.Ar procname .
	107	.It Fl z
	108	Do not skip zombies.
	109	This should not have any effect except to print a few error messages
	110	if there are zombie processes that match the specified pattern.
	111	.El
	112	.Sh ALL PROCESSES
	113	Sending a signal to all processes with uid
	114	.Em XYZ
	115	is already supported by
	116	.Xr kill 1 .
	117	So use
	118	.Xr kill 1
	119	for this job (e.g.\& $ kill -TERM -1 or
	120	as root $ echo kill -TERM -1 \| su -m <user>)
	121	.Sh EXIT STATUS
	122	The
	123	.Nm
	124	command will respond with a short usage message and exit with a status
	125	of 2 in case of a command error.
	126	A status of 1 will be returned if
	127	either no matching process has been found or not all processes have
	128	been signalled successfully.
	129	Otherwise, a status of 0 will be
	130	returned.
	131	.Sh DIAGNOSTICS
	132	Diagnostic messages will only be printed if requested by
	133	.Fl d
	134	options.
	135	.Sh SEE ALSO
	136	.Xr kill 1 ,
	137	.Xr sysctl 3
	138	.Sh HISTORY
	139	The
	140	.Nm
	141	command appeared in
	142	.Fx 2.1 .
	143	It has been modeled after the
	144	.Nm
	145	command as available on other platforms.
	146	.Sh AUTHORS
	147	.An -nosplit
	148	The
	149	.Nm
	150	program was originally written in Perl and was contributed by
	151	.An Wolfram Schneider ,
	152	this manual page has been written by
	153	.An J\(:org Wunsch .
	154	The current version of
	155	.Nm
	156	was rewritten in C by
	157	.An Peter Wemm
	158	using
	159	.Xr sysctl 3 .
