Background
We are moving from managing hosts by hand to configuration management.
20 files
I want to compare 20 times a config file from 20 hosts. For example /etc/crontab
Use case
I guess about 15 of 20 files are identical. I want to see the five files which where modified with "vi" by hand.
I want an overview, no automated action like patching ...
How to compare them ...?
I tried my favorit diff tool (meld), but it does not allow more than three files :-(
