KILL(1)                     NetBSD Reference 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 operand(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.

STANDARDS

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. NetBSD 1.4 April 28, 1995 1
