       kill ?-pgroup ?signal? idlist

              Send a signal to the each process in the list idlist, if permit-
              ted.  Signal, if present, is the signal number or  the  symbolic
              name of the signal, see the signal system call manual page.  The
              leading ``SIG'' is optional when the signal is specified by  its
              symbolic name.  The default for signo is 15, SIGTERM.

              If  -pgroup  is  specified,  the  numbers  in idlist are take as
              process group ids and the signal is sent to all of  the  process
              in  that  process  group.  A process group id of 0 specifies the
              current process group.

              The kill command is not available on Windows 95/NT.
