									KILL(1)                                                Linux User’s Manual                                  KILL(1)

          kill − send a signal to a process

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

          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 col-
          umn in ps command output. A PID of −1 is special; it indicates all processes except the kill process itself
          and init.

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

KILL(1)                                             Linux User’s Manual                                  KILL(1)

          XFSZ                   core        core dump might fail

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

          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.

          pkill(1), skill(1), kill(2), renice(1), nice(1), signal(7), killall(1).

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

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