40 .Nd terminate or signal a process
43 .Op Fl s Ar signal_name
57 utility sends a signal to the processes specified by the
61 Only the super-user may send signals to other users' processes.
63 The options are as follows:
64 .Bl -tag -width indent
65 .It Fl s Ar signal_name
66 A symbolic signal name specifying the signal to be sent instead of the
69 .It Fl l Op Ar exit_status
70 If no operand is given, list the signal names; otherwise, write
71 the signal name corresponding to
74 A symbolic signal name specifying the signal to be sent instead of the
77 .It Fl Ar signal_number
78 A non-negative decimal integer, specifying the signal to be sent instead
83 The following PIDs have special meanings:
84 .Bl -tag -width indent
86 If superuser, broadcast the signal to all processes; otherwise broadcast
87 to all processes belonging to the user.
90 Some of the more commonly used signals:
92 .Bl -tag -width indent -compact
102 KILL (non-catchable, non-ignorable kill)
106 TERM (software termination signal)
109 Some shells may provide a builtin
111 command which is similar or identical to this utility.
119 the processes with PIDs 142 and 157:
123 Send the hangup signal
125 to the process with PID 507:
127 .Dl "kill -s HUP 507"
129 Terminate the process group with PGID 117:
143 utility is expected to be
151 in section 8 of the manual.
153 A replacement for the command
157 users should be provided.
