 .Sh DESCRIPTION
-The kill utility sends the

+The
+.Nm
+utility sends a 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 s Ar signal_name
+A symbolic signal name specifying the signal to be sent instead of the
+default
+.Dv TERM .
+.It Fl l Op Ar exit_status
+If no operand is given, list the signal names; otherwise, write
+the signal name corresponding to
+.Ar exit_status .
 .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 .

-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)
+The following pids have special meanings:
+.Bl -tag -width Ds -compact
+.It -1
+If superuser, broadcast the signal to all processes; otherwise broadcast
+to all processes belonging to the user.
