For a single 69.Fl d 70option, a list of the processes that will be sent the signal will be 71printed, or a message indicating that no matching processes have been 72found. 73.It Fl h | ?\& | help 74Give a help on the command usage and exit. 75.It Fl l 76List the names of the available signals and exit, like in 77.Xr kill 1 . 78.It Fl m 79Match the argument 80.Ar procname 81as a (case insensitive) regular expression against the names 82of processes found. 83CAUTION! This is dangerous, a single dot will match any process 84running under the real UID of the caller. 85.It Fl s 86Show only what would be done, but do not send any signal. 87.It Fl SIGNAL 88Send a different signal instead of the default 89.Dv TERM . 90The signal may be specified either as a name 91(with or without a leading 92.Dv SIG ) , 93or numerically. 94.It Fl u Ar user 95Limit potentially matching processes to those belonging to 96the specified 97.Ar user . 98.It Fl t Ar tty 99Limit potentially matching processes to those running on 100the specified 101.Ar tty . 102.It Fl T 103Kill all processes on the current tty except ourselves or 104processes which parent us. 105.It Fl j Ar jailid 106Limit potentially matching processes to those running in the jail with id 107.Ar jailid . 108.It Fl c Ar procname 109When used with the 110.Fl u 111or 112.Fl t 113flags, limit potentially matching processes to those matching 114the specified 115.Ar procname . 116.El 117.Sh ALL PROCESSES 118Sending a signal to all processes with uid 119.Em XYZ 120is already supported by 121.Xr kill 1 . 122So use 123.Xr kill 1 124for this job (e.g. $ kill -TERM -1 or 125as root $ echo kill -TERM -1 | su -m <user>) 126.Sh DIAGNOSTICS 127The 128.Nm 129command will respond with a short usage message and exit with a status 130of 2 in case of a command error. A status of 1 will be returned if 131either no matching process has been found or not all processes have 132been signalled successfully.
