KILL(1) 						      General Commands Manual							   KILL(1)

NAME
kill - terminate a process with extreme prejudice SYNOPSIS
kill [ -sig ] processid ... kill -l DESCRIPTION
Kill sends the TERM (terminate, 15) signal to the specified processes. If a signal name or number preceded by `-' is given as first argu- ment, that signal is sent instead of terminate (see sigvec(2)). The signal names are listed by `kill -l', and are as given in /usr/include/signal.h, stripped of the common SIG prefix. The terminate signal will kill processes that do not catch the signal; `kill -9 ...' is a sure kill, as the KILL (9) signal cannot be caught. By convention, if process number 0 is specified, all members in the process group (i.e. processes resulting from the current login) are signaled (but beware: this works only if you use sh(1); not if you use csh(1).) Negative process numbers also have special meanings; see kill(2) for details. The killed processes must belong to the current user unless he is the super-user. The process number of an asynchronous process started with `&' is reported by the shell. Process numbers can also be found by using ps(1). 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 arguments. See csh(1) for details. SEE ALSO
csh(1), ps(1), kill(2), sigvec(2) BUGS
A replacement for ``kill 0'' for csh(1) users should be provided. 4th Berkeley Distribution April 20, 1986 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 process(es) 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] Display the name of the signal corresponding to exit_status. exit_status may be the exit status of a command killed by a signal (see the special sh(1) parameter '?') or a signal number. If no operand is given, display the names of all the signals. -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. 0 Broadcast the signal to all processes in the current process group 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), pgrep(1), pkill(1), ps(1), kill(2), sigaction(2), signal(7) STANDARDS
The kill function is expected to be IEEE Std 1003.2 (``POSIX.2'') compatible. HISTORY
A kill command appeared in Version 6 AT&T UNIX. BSD
April 28, 1995 BSD
