KILL linux command manual

KILL(1)                    Linux Programmer's Manual                   KILL(1)

       kill - terminate a process

       kill [ -s signal | -p ] [ -a ] [ -- ] pid ...
       kill -l [ signal ]

       The  command  kill sends the specified signal to the specified process
       or process group.  If no signal is specified, the TERM signal is sent.
       The  TERM  signal  will kill processes which do not catch this signal.
       For other processes, it may be necessary to use the KILL  (9)  signal,
       since this signal cannot be caught.

       Most  modern  shells have a builtin kill function, with a usage rather
       similar to that of the command  described  here.  The  '-a'  and  '-p'
       options,  and  the  possibility  to  specify pids by command name is a
       local extension.

       pid... Specify the list of processes that kill  should  signal.   Each
              pid can be one of five things:

              n      where  n  is larger than 0.  The process with pid n will
                     be signaled.

              0      All processes in the current process group are signaled.

              -1     All processes with pid larger than 1 will be signaled.

              -n     where  n  is  larger  than  1.  All processes in process
                     group n are signaled.  When an argument of the form '-n'
                     is  given,  and  it  is meant to denote a process group,
                     either the signal must be specified first, or the  argu-
                     ment  must  be  preceded  by a '--' option, otherwise it
                     will be taken as the signal to send.

                     All processes invoked using that name will be  signaled.

       -s signal
              Specify  the signal to send.  The signal may be given as a sig-
              nal name or number.

       -l     Print  a  list  of  signal   names.    These   are   found   in

       -a     Do  not restrict the commandname-to-pid conversion to processes
              with the same uid as the present process.

       -p     Specify that kill should only print the process id (pid) of the
              named processes, and not send any signals.

       Taken from BSD 4.4.  The ability to translate process names to process
       ids was added by Salvatore Valente .
