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 | ?\& 74.It Fl help 75Give a help on the command usage and exit. 76.It Fl l 77List the names of the available signals and exit, like in 78.Xr kill 1 . 79.It Fl m 80Match the argument 81.Ar procname 82as a (case insensitive) regular expression against the names 83of processes found. 84CAUTION! This is dangerous, a single dot will match any process 85running under the real UID of the caller. 86.It Fl s 87Show only what would be done, but do not send any signal. 88.It Fl SIGNAL 89Send a different signal instead of the default 90.Dv TERM . 91The signal may be specified either as a name 92(with or without a leading 93.Dv SIG ) , 94or numerically. 95.It Fl u Ar user 96Limit potentially matching processes to those belonging to 97the specified 98.Ar user . 99.It Fl t Ar tty 100Limit potentially matching processes to those running on 101the specified 102.Ar tty . 103.It Fl j Ar jailid 104Limit potentially matching processes to those running in the jail with id 105.Ar jailid . 106.It Fl c Ar procname 107When used with the 108.Fl u 109or 110.Fl t 111flags, limit potentially matching processes to those matching 112the specified 113.Ar procname . 114.El 115.Sh ALL PROCESSES 116Sending a signal to all processes with uid 117.Em XYZ 118is already supported by 119.Xr kill 1 . 120So use 121.Xr kill 1 122for this job (e.g. $ kill -TERM -1 or 123as root $ echo kill -TERM -1 | su -m <user>) 124.Sh DIAGNOSTICS 125The 126.Nm 127command will respond with a short usage message and exit with a status 128of 2 in case of a command error. A status of 1 will be returned if 129either no matching process has been found or not all processes have 130been signalled successfully. Otherwise, a status of 0 will be 131returned. 132.Pp 133Diagnostic messages will only be printed if requested by 134.Fl d 135options. 136.Sh SEE ALSO 137.Xr kill 1 , 138.Xr sysctl 3 139.Sh HISTORY 140The 141.Nm 142command appeared in 143.Fx 2.1 . 144It has been modeled after the 145.Nm 146command as available on other platforms. 147.Sh AUTHORS 148.An -nosplit 149The 150.Nm 151program was originally written in Perl and was contributed by 152.An Wolfram Schneider , 153this manual page has been written by 154.An J\(:org Wunsch . 155The current version of 156.Nm 157was rewritten in C by 158.An Peter Wemm 159using 160.Xr sysctl 3 . 161
