KILLALL(1)			   BSD General Commands Manual			       KILLALL(1)

NAME
     killall -- kill processes by name

SYNOPSIS
     killall [-d | -v] [-h | -?] [-help] [-l] [-m] [-s] [-u user] [-t tty] [-c procname]
	     [-SIGNAL] [procname ...]

DESCRIPTION
     Killall 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 mes-
		       sage indicating that no matching processes have been found.

	   -h | -?

	   -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 insensitive) regular expression
		       against the names of processes found.  CAUTION!	This is dangerous, a sin-
		       gle 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 signal.

	   -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 numeri-
		       cally.

	   -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 progname.

ALL PROCESSES
     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>)

DIAGNOSTICS
     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.

SEE ALSO
     kill(1), sysctl(3)

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

AUTHORS
     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 sysctl(3).
