NAME
kill - send a signal to a processSYNOPSIS
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

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.

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.Please send bug reports to <procps-feedback@lists.sf.net>
