+.Sh NAME
+.Nm kill
+.Nd terminate or signal a process
+.Sh SYNOPSIS
+.Nm kill
+.Op Fl signal_name
+.Ar pid
+\&...
+.Nm kill
+.Op Fl signal_number
+.Ar pid
+\&...
+.Nm kill
+.Op Fl l
+.Sh DESCRIPTION
+The kill utility sends the
+.Dv TERM
+signal to the processes specified
+by the pid operand(s).
+.Pp
+Only the super-user may send signals to other users' processes.
+.Pp
+The options are as follows:
+.Pp
+.Bl -tag -width Ds
+.It Fl l
+List the signal names.
+.It Fl signal_name
+A symbolic signal name specifying the signal to be sent instead of the
+default
+.Dv TERM .
+The
+.Fl l
+option displays the signal names.
+.It Fl signal_number
+A non-negative decimal integer, specifying the signal to be sent instead
+of the default
+.Dv TERM .
+.El
+.Pp
+Some of the more commonly used signals:
+.Bd -ragged -offset indent -compact
+.Bl -column XXX TERM
+.It -1 -1 (super-user broadcast to all processes, or user broadcast
+to user's processes)
+.It 0 0 (sh(1) only, signals all members of process group)
+.It 2 INT (interrupt)
+.It 3 QUIT (quit)
+.It 6 ABRT (abort)
+.It 9 KILL (non-catchable, non-ignorable kill)
+.It 14 ALRM (alarm clock)
+.It 15 TERM (software termination signal)
+.El
+.Ed
+.Pp
+.Nm Kill
+is a built-in to
+.Xr csh 1 ;
+it allows job specifiers of the form ``%...'' as arguments
+so process id's are not as often used as
+.Nm kill
+arguments.
+See
+.Xr csh 1
+for details.
+.Sh SEE ALSO
+.Xr csh 1 ,
+.Xr ps 1 ,
+.Xr kill 2 ,
+.Xr sigvec 2
+.Sh HISTORY
+A
+.Nm kill
+command appeared in
+.At v6 .
+.Sh BUGS
+A replacement for the command
+.Dq Li kill 0
+for
+.Xr csh 1
+users should be provided.
