For a single 64.Fl d 65option, a list of the processes that will be sent the signal will be 66printed, or a message indicating that no matching processes have been 67found. 68.It Fl h | ?\& 69.It Fl help 70Give a help on the command usage and exit. 71.It Fl l 72List the names of the available signals and exit, like in 73.Xr kill 1 . 74.It Fl m 75Match the argument 76.Ar procname 77as a (case insensitive) regular expression against the names 78of processes found. 79CAUTION! This is dangerous, a single dot will match any process 80running under the real UID of the caller. 81.It Fl s 82Show only what would be done, but do not send any signal. 83.It Fl SIGNAL 84Send a different signal instead of the default 85.Dv TERM . 86The signal may be specified either as a name 87(with or without a leading 88.Dv SIG ) , 89or numerically. 90.It Fl u Ar user 91Limit potentially matching processes to those belonging to 92the specified 93.Ar user . 94.It Fl t Ar tty 95Limit potentially matching processes to those running on 96the specified 97.Ar tty . 98.It Fl c Ar procname 99When used with the 100.Fl u 101or 102.Fl t 103flags, limit potentially matching processes to those matching 104the specified 105.Ar progname . 106.El 107.Sh ALL PROCESSES 108Sending a signal to all processes with uid 109.Nm XYZ 110is already supported by 111.Xr kill 1 . 112So use 113.Xr kill 1 114for this job (e.g. $ kill -TERM -1 or 115as root $ echo kill -TERM -1 | su -m <user>) 116.Sh DIAGNOSTICS 117The 118.Nm 119command will respond with a short usage message and exit with a status 120of 2 in case of a command error. A status of 1 will be returned if 121either no matching process has been found or not all processes have 122been signalled successfully. Otherwise, a status of 0 will be 123returned. 124.Pp 125Diagnostic messages will only be printed if requested by 126.Fl d 127options. 128.Sh SEE ALSO 129.Xr kill 1 , 130.Xr sysctl 3 131.Sh HISTORY 132The 133.Nm 134command appeared in 135.Fx 2.1 . 136It has been modeled after the 137.Nm 138command as available on other platforms. 139.Sh AUTHORS 140.An -nosplit 141The 142.Nm 143program was originally written in Perl and was contributed by 144.An Wolfram Schneider , 145this manual page has been written by 146.An J\(:org Wunsch . 147The current version of 148.Nm 149was rewritten in C by 150.An Peter Wemm 151using 152.Xr sysctl 3 . 153
