NAME

       kill - send a signal to a process

SYNOPSIS

       kill [options] <pid> [...]

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 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

       <pid> [...]
              Send signal to every <pid> listed.

       -<signal>
       -s <signal>
       --signal <signal>
              Specify  the  signal  to  be  sent.   The  signal can be specified by using name or
              number.  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.
