NAME

filechan - file-writing backend for InterNetNews
 

SYNOPSIS

DESCRIPTION

Filechan input is interpreted as a set of lines. Each line contains a fixed number of initial fields, followed by a variable number of filename fields. All fields in a line are separated by whitespace. The default number of initial fields is one.

For each line of input, filechan writes the initial fields, separated by whitespace and followed by a newline, to each of the files named in the filename fields. When writing to a file, filechan opens it in append mode and tries to lock it and change the ownership to the user and group who owns the directory where the file is being written.  

OPTIONS

-f

The ``-f'' flag may be used to specify a different number of initial fields.

-d

By default, filechan writes its output into the directory <pathoutgoing in inn.conf>. The ``-d'' flag may be used to specify a directory the program should change to before starting.

-p

If the ``-p'' flag is used, the program will write a line containing its process ID (in text) to the specified file.

If filechan is invoked with ``-f 2'' and given the following input:

news/software/b/132 <1643@munnari.oz.au> foo uunet
news/software/b/133 <102060@litchi.foo.com> uunet munnari
comp/sources/unix/2002 <999@news.foo.com> foo uunet munnari

Then the file foo will have these lines:

news/software/b/132 <1643@munnari.oz.au>
comp/sources/unix/2002 <999@news.foo.com>

the file munnari will have these lines:

news/software/b/133 <102060@litchi.foo.com>
comp/sources/unix/2002 <999@news.foo.com>

and the file uunet will have these lines:

news/software/b/132 <1643@munnari.oz.au>
news/software/b/133 <102060@litchi.foo.com>
comp/sources/unix/2002 <999@news.foo.com>

Because the time window in which a file is open is very small, complicated flushing and locking protocols are not needed; a mv(1) followed by a sleep(1) for a couple of seconds is sufficient.

-m

A map file may be specified by using the ``-m'' flag. Blank lines and lines starting with a number sign (``#'') are ignored. All other lines should have two host names separated by a colon. The first field is the name that may appear in the input stream; the second field names the file to be used when the name in the first field appears. For example, the following map file may be used to map the short names above to the full domain names:

# This is a comment
uunet:news.uu.net
foo:foo.com
munnari:munnari.oz.au
