NAME

kill - send a signal to a process

 

SYNOPSIS

kill [ -signal | -s signal ] pid ...
kill [ -L | -V, --version ]
kill -l [ signal ]

 

DESCRIPTION

The default signal for kill is TERM. Use -l or -L to list available signals. Particularly useful signals include HUP, INT, KILL, STOP, CONT, and 0. Alternate signals may be specified in three ways: -9 -SIGKILL -KILL. Negative PID values may be used to choose whole process groups; see the PGID column in ps command output. A PID of -1 is special; it indicates all processes except the kill process itself and init.

 

SIGNALS

The signals listed below may be available for use with kill. When known constant, numbers and default behavior are shown.

NOTES

Your shell (command line interpreter) may have a built-in kill command. You may need to run the command described here as /bin/kill to solve the conflict.

 

EXAMPLES

kill -9 -1
Kill all processes you can kill.
kill -l 11
Translate number 11 into a signal name.
kill -L
List the available signal choices in a nice table.
kill 123 543 2341 3453
Send the default signal, SIGTERM, to all those processes.

STANDARDS

This command meets appropriate standards. The -L flag is Linux-specific.

 

AUTHOR

Albert Cahalan <albert@users.sf.net> wrote kill in 1999 to replace a bsdutils one that was not standards compliant. The util-linux one might also work correctly.
