33 .Nd kill processes by name
52 utility kills processes selected by name, as opposed to the selection by pid
55 By default, it will send a
57 signal to all processes with a real UID identical to the
62 The super-user is allowed to kill any process.
64 The options are as follows:
65 .Bl -tag -width 10n -offset indent
67 Do not print an error message if no matching processes are found.
69 Be more verbose about what will be done. For a single
71 option, a list of the processes that will be sent the signal will be
72 printed, or a message indicating that no matching processes have been
76 Give a help on the command usage and exit.
78 List the names of the available signals and exit, like in
83 as a (case insensitive) regular expression against the names
85 CAUTION! This is dangerous, a single dot will match any process
86 running under the real UID of the caller.
88 Show only what would be done, but do not send any signal.

128 command will respond with a short usage message and exit with a status
129 of 2 in case of a command error. A status of 1 will be returned if
130 either no matching process has been found or not all processes have
131 been signalled successfully. Otherwise, a status of 0 will be
