kill [ -s signal name ] job ...
kill [ -sig ] job ...
kill -l [ sig ... ]
       Sends either SIGTERM or the specified signal to the
       given jobs or processes.  Signals are given by num-
       ber  or by names, without the `SIG' prefix.  If the
       signal being sent is not `KILL' or `CONT', then the
       job  will be sent a `CONT' signal if it is stopped.
       The argument job can be the process ID of a job not
       in  the  job  list.  In the third form, kill -l, if
       sig is not specified the signal names  are  listed.
       Otherwise,  for each sig that is a name, the corre-
       sponding signal number is  listed.   For  each  sig
       that  is  a  signal number or a number representing
       the exit status of a process which  was  terminated
       or  stopped  by  a signal the name of the signal is
       printed.
