kill(1)

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.
