Posting-number: Volume 6, Issue 18 Submitted-by: edw@wells.UUCP (Ed Wells) Archive-name: news2path [Beware of this "shar" format... ++bsa] ---- Cut Here and unpack ---- #!/bin/sh # shar: Shell Archiver (v1.22) # # Run the following text with /bin/sh to create: # read.me # usa.paths # pa.paths # news2path.c # echo "x - extracting read.me (Text)" sed 's/^X//' << 'SHAR_EOF' > read.me && X X X X X X X X X X X X X X X Here's a little program that I wrote to use the information stored X in /usr/spool/news/comp/mail/maps/* directly without having to build a X second set of files nearly totaling the same size. X X This program extracts only the information that is needed to X rebuild a pathalias file. It extracts from whatever files are present X removing the headers, shar information and all lines that start with a X '#' sign. This leaves only the minimal amount of information needed to X start building a paths file. X X I also have two shell scripts that I have provided. Both of these X shell programs accept one argument which is the target system name. X Each shell is used to filter the listing down to either just 'usa' list- X ings or 'usa.pa' (Pennsylvania) listings. I also have the program look X for a file named 'local.$1' where $1 gets replaced with the target name X I am building a file for. It's in this file that I normally put all of X the unlisted/private/local connections to each system that I am building X a paths file for. I also list the 'smart-host' system here also for X each system. X X When I'm done, I just take the file named 'paths.$1' (where $1 is X replaced with the target name) and install it in my /usr/lib/uucp/paths X file or send it to the remote site requiring a path. X X This source code is the property of Wells Computer Systems Corp. X and is being released to the Usenet community for any not-for-profit X use. X X If you add anything to this, please submit it back to me. X Enjoy.
