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 op‐
     erand(s).

     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)

     Kill is a built-in to csh(1); it allows job specifiers of the form
     ``%...'' as arguments so process id's are not as often used as kill argu‐
     ments.  See csh(1) for details.

SEE ALSO
     csh(1), ps(1), kill(2), sigvec(2)

STANDARDS
     The kill function is expected to be IEEE Std 1003.2 (“POSIX.2”) compati‐
     ble.

HISTORY
     A kill command appeared in Version 6 AT&T UNIX.

BUGS
     A replacement for the command “kill 0” for csh(1) users should be pro‐
     vided.
