KILL(1)                 COMMAND REFERENCE                 KILL(1)



NAME
     kill - terminate a process with extreme prejudice

SYNOPSIS
     kill [ -sig ] processid ...
     kill -l

DESCRIPTION
     Kill sends the TERM (terminate, 15) signal to the specified
     processes.  If a signal name or number preceded by `-' is
     given as first argument, that signal is sent instead of
     terminate (see signal(3c)).  The signal names are listed by
     `kill -l', and are as given in /usr/include/signal.h,
     stripped of the common SIG prefix.

     The terminate signal will kill processes that do not catch
     the signal; `kill -9 ...' is a sure kill, as the KILL (9)
     signal cannot be caught.  By convention, if process number 0
     is specified, all members in the process group (i.e.
     processes resulting from the current login) are signaled.
     The killed processes must belong to the current user unless
     he is the super-user.

     To shut the system down and bring it up single user the
     super-user may send the initialization process a TERM
     (terminate) signal by `kill 1'; see init(8).  To force init
     to close and open terminals according to what is currently
     in /etc/ttys use `kill -HUP 1' (sending a hangup (which is
     signal number 1) to process number 1).

     The process number of an asynchronous process started with
     `&' is reported by the shell.

OPTIONS
     -l   Lists the signal names.

     -sig The specified signal is sent to the specified process.

EXAMPLES
     The following example absolutely terminates process number
     186.

          kill -9 186

     This example shows a shell script that can be used to log
     off of the system by sending the hangup signal to the
     process group.

          #!/bin/sh
          echo "Logging off..."
          kill -HUP 0
