For a single 66.Fl d 67option, a list of the processes that will be sent the signal will be 68printed, or a message indicating that no matching processes have been 69found. 70.It Fl h | ?\& 71.It Fl help 72Give a help on the command usage and exit. 73.It Fl l 74List the names of the available signals and exit, like in 75.Xr kill 1 . 76.It Fl m 77Match the argument 78.Ar procname 79as a (case insensitive) regular expression against the names 80of processes found. 81CAUTION! This is dangerous, a single dot will match any process 82running under the real UID of the caller. 83.It Fl s 84Show only what would be done, but do not send any signal. 85.It Fl SIGNAL 86Send a different signal instead of the default 87.Dv TERM . 88The signal may be specified either as a name 89(with or without a leading 90.Dv SIG ) , 91or numerically. 92.It Fl u Ar user 93Limit potentially matching processes to those belonging to 94the specified 95.Ar user . 96.It Fl t Ar tty 97Limit potentially matching processes to those running on 98the specified 99.Ar tty . 100.It Fl c Ar procname 101When used with the 102.Fl u 103or 104.Fl t 105flags, limit potentially matching processes to those matching 106the specified 107.Ar procname . 108.It Fl z 109Do not skip zombies. 110This should not have any effect except to print a few error messages 111if there are zombie processes that match the specified pattern. 112.El 113.Sh ALL PROCESSES 114Sending a signal to all processes with uid 115.Em XYZ 116is already supported by 117.Xr kill 1 . 118So use 119.Xr kill 1 120for this job (e.g. $ kill -TERM -1 or 121as root $ echo kill -TERM -1 | su -m <user>) 122.Sh DIAGNOSTICS 123The 124.Nm 125command will respond with a short usage message and exit with a status 126of 2 in case of a command error. A status of 1 will be returned if 127either no matching process has been found or not all processes have 128been signalled successfully. Otherwise, a status of 0 will be 129returned. 130.Pp 131Diagnostic messages will only be printed if requested by 132.Fl d 133options. 134.Sh SEE ALSO 135.Xr kill 1 , 136.Xr sysctl 3 137.Sh HISTORY 138The 139.Nm 140command appeared in 141.Fx 2.1 . 142It has been modeled after the 143.Nm 144command as available on other platforms. 145.Sh AUTHORS 146.An -nosplit 147The 148.Nm 149program was originally written in Perl and was contributed by 150.An Wolfram Schneider , 151this manual page has been written by 152.An J\(:org Wunsch . 153The current version of 154.Nm 155was rewritten in C by 156.An Peter Wemm 157using 158.Xr sysctl 3 . 159
