[mrtg] Comparing *.cfg files

[fluhmann at vvm.com]

I'm trying to compare two config files: mrtg.cfg mrtg.old.
I want to:
 1) Compare to see if any interfaces have been added or moved.
 2) If any have been added, create a new *.rrd for them.
 3) If any have been moved, try to find out what interface they are now.
  (ex. xxx.xxx_12 changed to xxx.xxx_14)
 4) Rename the old *.rrd to the new interface name.
  (ex. xxx.xxx_12.rrd renamed to xxx.xxx_14.rrd)
 5) If an *.rrd with the same name as the new one exists, add the
extension .tmp
  (ex. xxx.xxx_14 already existed, then rename it to xxx.xxx_14.rrd.tmp)
I've tried using a perl script for this, but when I ran it, some things
went wrong.

You can look at my code here: http://www.vvm.com/~fluhmann/mrtg.txt

If anyone has any ideas of ways of doing this, please let me know.

Thank you so much.
