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

NAME

     killall -- kill processes by name

SYNOPSIS

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

DESCRIPTION

     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.

     -I 	  Request confirmation before attempting to signal each process.

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

     -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 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 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.

     -q 	  Suppress error message if no processes are matched.

     -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

     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>'').

IMPLEMENTATION NOTES

     This FreeBSD implementation of killall has completely different semantics as compared to the traditional UNIX System V behavior of killall.
     The latter will kill all processes that the current user is able to kill, and is intended to be used by the system shutdown process only.

EXIT STATUS

     The killall utility exits 0 if some processes have been found and signalled successfully.	Otherwise, a status of 1 will be returned.

DIAGNOSTICS

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

SEE ALSO

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

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).

NAME

       killall - Terminates all processes started by the user, except the calling process

SYNOPSIS

       /usr/sbin/killall [- | [-]signal_name | -signal_number]

       /usr/sbin/killall -l

FLAGS

       The  hyphen  character (without an argument) sends a SIGTERM signal initially and then sends a SIGKILL signal to all processes that survive
       for 30 seconds after receipt of the first signal.  This gives processes that catch the SIGTERM signal an opportunity to clean up.  A signal
       name, optionally preceded by a hyphen, sends the specified signal to processes.	The hyphen character (with a signal number argument) sends
       the specified signal, either a name, stripped of the SIG prefix (such as KILL), or a number (such as  9).   For	information  about  signal
       names and numbers, see the signal() system call.

       In  the System V habitat, the optional signal number does not have to be preceded with a hyphen (-).  Lists signal names in numerical order
       (as given in the /usr/include/signal.h file), stripped of the common SIG prefix.

DESCRIPTION

       This command provides a convenient means of killing all processes created by the shell that you control.  When started  by  the	superuser,
       the killall command kills all processes that can be terminated, except those processes that started it, the kernel processes, and processes
       0 and 1 (init).

   Security Configuration
       This command is modified in all security configurations of the system.

EXAMPLES

       To stop all background processes that have started, enter: killall This sends all background processes signal  9  (the  kill  signal,  also
       called  SIGKILL).   To  stop  all  background processes, giving them a chance to clean up, enter: killall - This sends signal 15 (SIGTERM),
       waits 30 seconds, and then sends signal 9 (SIGKILL).  To send a specific signal to the background processes, enter: killall -2  This  sends
       signal  2 (SIGINT) to the background processes.	To list the signal names in numerical order, stripped of the SIG prefix, enter: killall -l
       This displays a list of signals, which may vary from system to system.
