+.TH KILL 1 
+.SH NAME
+kill \- terminate a process with extreme prejudice
+.SH SYNOPSIS
+.B kill
+[
+.BR \- signo
+]
+processid ...
+.SH DESCRIPTION
+.I Kill
+sends signal 15 (terminate) to the specified processes.
+If a signal number preceded by `\-' is given
+as first argument, that signal is sent instead of
+terminate
+(see
+.IR  signal (2)).
+This will kill processes that do not catch the signal;
+in particular `kill \-9 ...' is a sure kill.
+.PP
+By convention, if process number 0 is specified, all members
+in the process group (i.e. processes resulting from 
+the current login) are signaled.
+.PP
+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
+use `kill \-1 1'; see
+.IR init (8).
+.PP
+The process number of an asynchronous process
+started with `&' is reported by the shell.
+Process numbers can also be found by using
+.IR ps (1).
