Regexp Cheatsheet is a helpful blog post on Basic Regular Expressions (BRE) and Extended Regular Expressions (ERE) syntax supported by GNU grep, sed and awk. It covers the differences between these somewhat complex tools — for example, awk doesn't support backreferences within regexp definition (i.e., the search portion). Kindly shared by its author, ASIC_SP.
