File comparison tool

Hi all.

I need to monitor the configuration of 100+ sites (cisco routers) on almost daily basis. I will be saving the base config and then need to compare by downloading the config of every site.

I have used Rancid for downloading the config. Now i need some other tool ( i know rancid provides diff to check the difference but still).

The file comparison tool should ignore blank space, carriage line feeds, spaces, tabs.

Can someone pls refer me a good tool for that ?

Just a few come to mind; grep, diff, maybe egrep. Oh, and sort!

grep -v "^#" /path/to/config1 | tee -a ~/config1
grep -v "^#" /path/to/config2 | tee -a ~/config2
diff ~/config1 ~/config2
You could also setup a "Version Control" repository like SVN or CVS to store the configuration files into, and then you could do compares between "versions".
