KILL(1)                                   User Commands                                   KILL(1)

NAME
       kill - send a signal to a process

SYNOPSIS
       kill [options]  [...]

DESCRIPTION
       The  default  signal  for kill is TERM.  Use -l or -L to list available signals.  Particu‐
       larly useful signals include HUP, INT, KILL, STOP, CONT, and 0.  Alternate signals may  be
       specified in three ways: -9, -SIGKILL or -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.

OPTIONS
        [...]
              Send signal to every  listed.

       -
       -s 
       --signal 
              Specify  the  signal to be sent.  The signal can be specified by using name or num‐
              ber.  The behavior of signals is explained in signal(7) manual page.

       -l, --list [signal]
              List signal names.  This option has optional argument, which  will  convert  signal
              number to signal name, or other way round.

       -L, --table
              List signal names in a nice table.

       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.
