.Sh DESCRIPTION
1996-12-14 06:01:00 +00:00
The

utility sends a signal to the processes specified by the
.Ar pid
operand(s).
1994-05-26 06:18:55 +00:00

Only the super-user may send signals to other users' processes.
.Pp
The options are as follows:
.Pp
.Bl -tag -width Ds
1996-12-14 06:01:00 +00:00
.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 Ar signal_name
1994-05-26 06:18:55 +00:00
A symbolic signal name specifying the signal to be sent instead of the

.Pp
Send the hangup signal
.Pq Dv SIGHUP
to the process with pid 507:
