NAME    [Toc]    [Back]

     killall -- kill processes by name

SYNOPSIS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

     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.

	   -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 single dot will
		       match any process running under the real UID of the

	   -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 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 zombie
 processes that match the specified pattern.

ALL PROCESSES    [Toc]    [Back]

     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    [Toc]    [Back]

     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 as available on other platforms.
