An easy way to diff log files, ignoring the time stamps?

Question

I need to diff two log files but ignore the time stamp part of each line (the first 12 characters to be exact). Is there a good tool, or a clever awk command, that could help m

Answer 1

For a graphical option, Meld can do this using its text filters feature.

It allows for ignoring lines based on one or more python regex. The differences still appear, but lines that don't have any other differences won't be highlighted.
