kill - send signals to a process

NAME SYNOPSIS DESCRIPTION OPTIONS AND ARGUMENTS NOTES HISTORY AUTHOR SEE ALSO

SYNOPSIS

kill [ −s signalname "PID..." ] [ −signalname "PID..." ] [ −signalnumber "PID..." ] [ "PID..." ] [ −l ]

kill sends a signal to all PIDS specified on the command line. This is typically done to cause a process to terminate and/or to reload configuration files, etc. Signal handlers are specified per program, so the effects of a received signal may vary.

OPTIONS AND ARGUMENTS

−s

This parameter takes a single argument of a signal name (see −l)

to be sent to the specified PIDs.

	−signalname			A short form of the "−s signalname" parameter.
	−signalnumber			This parameter specifies that the given signal number

should be sent to the specified PID listing.

−l

Display a listing of all available signals on the current system.

NOTES

If no signal is specified on the command line, SIGTERM is sent to the specified PIDs.

kill returns 0 on success or >0 if an error occurred.

kill is built−in to csh(1); See csh(1) for details.

Only the super−user may send signals to other users' processes.

This version of kill does not support −l [signal] since there didn't seem to be any use to the parameter (it didn't work on any platform I tried either.)

Signal names may have the SIG prefix. i.e.: "kill −HUP" and "kill −SIGHUP" are equivalent.

The signal list "kill −l" displays in an "extended" form which lists both the signal name and the signal number for easy reference.

HISTORY

Perl version rewritten for the Perl Power Tools project from the description of the kill program in OpenBSD.
