NAME
kill -- terminate or signal a process
SYNOPSIS
kill [-s signal_name] pid ...
kill -l [signal_number]
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 [signal_number]
If no operand is given, list the signal names; otherwise, write
the signal name corresponding to signal_number provided.
-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.
