Have you ever done something like this?
$ grep somestring file1 > /tmp/a
$ grep somestring file2 > /tmp/b
$ diff /tmp/a /tmp/b
That works, but instead you can write:
diff <(grep somestring file1) <(grep somestring file2)
Isnt that neater?

Good post that one! Bookmarked! :) I've been also reading about scripting lately, trying to learn the basics. I came across this site https://www.cheatography.com/explore/tags/  which has a lot of "cheat sheets" and I've been reading here too https://www.codecademy.com/
