43 .Op Fl s Ar signal_name
60 utility sends a signal to the process(es) specified
61 by the pid operand(s).
63 Only the super-user may send signals to other users' processes.
65 The options are as follows:
67 .It Fl s Ar signal_name
68 A symbolic signal name specifying the signal to be sent instead of the

72 Display the name of the signal corresponding to
75 may be the exit status of a command killed by a signal

94 The following pids have special meanings:
95 .Bl -tag -width Ds -compact
97 If superuser, broadcast the signal to all processes; otherwise broadcast
98 to all processes belonging to the user.
100 Broadcast the signal to all processes in the current process group
101 belonging to the user.
104 Some of the more commonly used signals:

129 so process id's are not as often used as
