Regex Cheat Sheet (Printable PDF)

For the pattern that works everywhere except where you need it.

Use it when: a grep matches too much or too little, you need to pull one field out of a line, a pattern breaks on a different engine.

On the sheet: anchors, character classes, quantifiers, groups and more.

Not on it: language-specific regex engines beyond POSIX and PCRE basics.
