KILLALL(1)		FreeBSD	General	Commands Manual		    KILLALL(1)

     killall --	kill processes by name

     killall [-delmsvz]	[-help]	[-j jid] [-u user] [-t tty] [-c	procname]
	     [-SIGNAL] [procname ...]

     The killall utility kills processes selected by name, as opposed to the
     selection by pid as done by kill(1).  By default, it will send a TERM
     signal to all processes with a real UID identical to the caller of
     killall that match	the name procname.  The	super-user is allowed to kill
     any process.

     The options are as	follows:

	   -d |	-v     Be more verbose about what will be done.	 For a single
		       -d option, a list of the	processes that will be sent
		       the signal will be printed, or a	message	indicating
		       that no matching	processes have been found.

	   -e	       Use the effective user ID instead of the	(default) real
		       user ID for matching processes specified	with the -u

	   -help       Give a help on the command usage	and exit.

	   -l	       List the	names of the available signals and exit, like
		       in kill(1).

	   -m	       Match the argument procname as a	(case sensitive) regu-
		       lar expression against the names	of processes found.
		       CAUTION!	 This is dangerous, a single dot will match
		       any process running under the real UID of the caller.

	   -s	       Show only what would be done, but do not	send any sig-

	   -SIGNAL     Send a different	signal instead of the default TERM.
		       The signal may be specified either as a name (with or
		       without a leading SIG), or numerically.

	   -j jid      Kill processes in the jail specified by jid.

	   -u user     Limit potentially matching processes to those belonging
		       to the specified	user.

	   -t tty      Limit potentially matching processes to those running
		       on the specified	tty.

	   -c procname
		       When used with the -u or	-t flags, limit	potentially
		       matching	processes to those matching the	specified

	   -z	       Do not skip zombies.  This should not have any effect
		       except to print a few error messages if there are zom-
		       bie processes that match	the specified pattern.

     Sending a signal to all processes with uid	XYZ is already supported by
     kill(1).  So use kill(1) for this job (e.g. $ kill	-TERM -1 or as root $
     echo kill -TERM -1	| su -m	<user>)

     The killall command will respond with a short usage message and exit with
     a status of 2 in case of a	command	error.	A status of 1 will be returned
     if	either no matching process has been found or not all processes have
     been signalled successfully.  Otherwise, a	status of 0 will be returned.

     Diagnostic	messages will only be printed if requested by -d options.

     The killall command appeared in FreeBSD 2.1.  It has been modeled after
     the killall command as available on other platforms.

     The killall program was originally	written	in Perl	and was	contributed by
     Wolfram Schneider,	this manual page has been written by Jorg Wunsch.  The
     current version of	killall	was rewritten in C by Peter Wemm using
