CLI tool for 'diffing' in a useful fashion: vimdiff

Had to scratch my head to find the right tool for the job today - something that I used regularly at SMX but havn't had much need to use since.

The tool was 'vimdiff'. I needed to compare to configuration files (retrieved from two different servers) to understand what difference existed. Whilst 'diff' alone would've done it, I find the output hard to follow. vimdiff worked wonders!

Google hit I used also has some other useful tools:

For posterity.

Honourable mention for icdiff also.
