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 Terminate the process group with PGID 117: kill -- -117 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. BSD

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
