NAME
     kill - send a signal to a process, or terminate a process

SYNOPSIS
     kill [ -signal ] pid ...
     kill -l

DESCRIPTION
     kill sends the TERM (terminate, 15) signal to the  processes
     with  the  specified  pids.  If a signal name or number pre-
     ceded by `-' is given as first argument, that signal is sent
     instead  of terminate.  The signal names are listed by using
     the -l option, and are as given in <signal.h>,  stripped  of
     the common SIG prefix.

     The terminate signal will kill processes that do  not  catch
     the signal, so `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 (that is,
     processes resulting from the  current  login)  are  signaled
     (but  beware:  this  works only if you use sh(1); not if you
     use csh(1).) Negative  process  numbers  also  have  special
     meanings;  see  kill(2V)  for details.  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 (ter-
     minate) signal by `kill 1'; see init(8).  To force  init  to
     close  and  open terminals according to what is currently in
     /etc/ttytab use `kill -HUP 1' (sending a  hangup  signal  to
     process 1).

     The shell reports the process number of an asynchronous pro-
     cess  started  with  `&'  (run  in the background).  Process
     numbers can also be found by using ps(1).

     kill is built in to csh(1); it allows job  specifiers,  such
     as  `kill   %  ...', in place of kill arguments.  See csh(1)
     for details.

BUGS
     A replacement for `kill  0' for csh(1) users should be  pro-
     vided.
