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

     killall — kill processes by name

     killall [-delmsvz] [-help] [-j jail] [-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 option.

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

     -l		  List the names of the available signals and exit, like in

     -m		  Match the argument procname as a (case sensitive) regular
		  expression against the names of processes found.  CAUTION!
		  This is dangerous, a single dot will match any process run‐
		  ning 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 numerically.

     -j jail	  Kill processes in the specified jail.

     -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  Limit potentially matching processes to those matching the
		  specified procname.

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

     Sending a signal to all processes with the given UID 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 utility exits 0 if some processes have been found and sig‐
     nalled successfully.  Otherwise, a status of 1 will be returned.

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

     kill(1), pkill(1), sysctl(3), jail(8)

     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 Jörg Wunsch.  The
     current version of killall was rewritten in C by Peter Wemm using
