For even longer ones I just started using perl with /x, so you can uses insignificant whitespace and comments.
- shmerl 12y agoI didn't really compare, since grep marks --perl as "highly experimental". pcregrep on the other hand is around for a long time already. One very useful feature in pcregrep is outputting the matched subpattern only. For example if you do: echo 'abcdefg' | pcregrep -o2 'a(bc)d(ef)g' It will output only second matched subpattern.
