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

Use Kdiff3 and at Configure>Diff edit "Line-Matching Preprocessor command" to something like:

sed "s/[ 012][0-9]:[0-5][0-9]:[0-5][0-9]//"

This will filter out time-stamps from comparison alignment algorithm.

Kdiff3 also lets you manually align specific lines.
