kill

KILL(1) 						    BSD General Commands Manual 						   KILL(1)

NAME

     kill -- terminate or signal a process

SYNOPSIS

     kill [-s signal_name] pid ...
     kill -l [exit_status]
     kill -signal_name pid ...
     kill -signal_number pid ...

DESCRIPTION

     The kill utility sends a signal to the processes specified by the pid operands.

     Only the super-user may send signals to other users' processes.

     The options are as follows:

     -s signal_name
	     A symbolic signal name specifying the signal to be sent instead of the default TERM.

     -l [exit_status]
	     If no operand is given, list the signal names; otherwise, write the signal name corresponding to exit_status.

     -signal_name
	     A symbolic signal name specifying the signal to be sent instead of the default TERM.

     -signal_number
	     A non-negative decimal integer, specifying the signal to be sent instead of the default TERM.

     The following PIDs have special meanings:

     -1      If superuser, broadcast the signal to all processes; otherwise broadcast to all processes belonging to the user.

     Some of the more commonly used signals:

     1	     HUP (hang up)
     2	     INT (interrupt)
     3	     QUIT (quit)
     6	     ABRT (abort)
     9	     KILL (non-catchable, non-ignorable kill)
     14      ALRM (alarm clock)
     15      TERM (software termination signal)

     Some shells may provide a builtin kill command which is similar or identical to this utility.  Consult the builtin(1) manual page.

EXIT STATUS

     The kill utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

     Terminate the processes with PIDs 142 and 157:

	   kill 142 157

     Send the hangup signal (SIGHUP) to the process with PID 507:

	   kill -s HUP 507

SEE ALSO

     builtin(1), csh(1), killall(1), ps(1), sh(1), kill(2), sigaction(2)

STANDARDS

     The kill utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible.

HISTORY

     A kill command appeared in Version 3 AT&T UNIX.

BUGS

     A replacement for the command ``kill 0'' for csh(1) users should be provided.
