44 .Nd terminate or signal a process
47 .Op Fl s Ar signal_name
61 utility sends a signal to the processes specified by the
65 Only the super-user may send signals to other users' processes.
67 The options are as follows:
68 .Bl -tag -width indent
69 .It Fl s Ar signal_name
70 A symbolic signal name specifying the signal to be sent instead of the
73 .It Fl l Op Ar exit_status
74 If no operand is given, list the signal names; otherwise, write
75 the signal name corresponding to
78 A symbolic signal name specifying the signal to be sent instead of the
81 .It Fl Ar signal_number
82 A non-negative decimal integer, specifying the signal to be sent instead
87 The following PIDs have special meanings:
88 .Bl -tag -width indent
90 If superuser, broadcast the signal to all processes; otherwise broadcast
91 to all processes belonging to the user.
94 Some of the more commonly used signals:
96 .Bl -tag -width indent -compact
106 KILL (non-catchable, non-ignorable kill)
110 TERM (software termination signal)
113 Some shells may provide a builtin
115 command which is similar or identical to this utility.
123 the processes with PIDs 142 and 157:
127 Send the hangup signal
129 to the process with PID 507:
131 .Dl "kill -s HUP 507"
133 Terminate the process group with PGID 117:
