       control.ctl - specify handling of Usenet control messages

       The  file  /var/spool/news/data/control.ctl  is	used to determine what
       action is taken when a control message is received.  It is read by  the
       parsecontrol  script, which is called by all the control scripts.  (For
       an explanation of how the control scripts are invoked, see innd(8).)

       The file consists of a series of lines; blank lines and lines beginning
       with  a	number	sign  (``#'') are ignored.  All other lines consist of
       four fields separated by a colon:

       The first field is the name of the  message  for	 which	this  line  is
       valid.	It  should  be	either the name of the control message, or the
       word ``all'' to mean that it is valid for all messaages.

       The second field is  a  shell-style  pattern  that  matches  the	 email
       address	of  the	 person posting the message.  (The poster's address is
       first converted to lowercase.)  The matching is done using the  shell's
       case statement; see sh (1) for details.

       If  the	control	 message is ``newgroup'' or ``rmgroup'' then the third
       field specifies the shell-style pattern that must match the group being
       created	or  removed.   If  the control message is of a different type,
       then this field is ignored.

       The fourth field specifies what action to take if this line is selected
       for the message.	 The following actions are understood:

       doit   The action requested by the control message should be performed.
	      In most cases the control script will also send mail to usenet.

	      If the control message has an argument, this  is	treated	 as  a
	      ``doit''	action.	  If no argument was given, it is treated as a
	      ``mail'' entry.  This is used in ``sendsys'' entries  script  so
	      that  a site can request its own newsfeeds(5) entry by posting a
	      ``sendsys	 mysite''  article.   On  the  other  hand,  ``sendsys
	      bombs''  ask  that  the  newsfeeds file be sent; by using ``doi‐
	      farg'' such messages will not be processed automatically.

	      The action is performed, but a log entry is written to the spec‐
	      ified  log  file,	 file.	 If file is the word ``mail'' then the
	      record is mailed.	 A null string is equivalent to /dev/null.   A
	      pathname that starts with a slash is taken as the absolute file‐
	      name to use as the log.  All  other  pathnames  are  written  to
	      /var/spool/news/data/file.log.   The  log is written by writelog
	      (see newslog(8)).

       drop   No action is taken; the message is ignored.

       log    A one-line log notice is sent to standard error.	Innd  normally
	      directs this to the file /var/spool/news/data/errlog.

	      A log entry is written to the specified log file, file, which is
	      interpreted as described above.

       mail   A mail message is sent to the news administrator.

       Lines are matched in order; the last match found in the file is the one
       that is used.  For example, with the following three lines:
       A  newgroup  coming from ``tale'' at a UUNET machine will be honored if
       it is in one the mainstream Usenet hieararchy.  If ``kre'' posts a new‐
       group  message creating ``'', then mail will be sent.  All other
       newgroup messages are ignored.
