Cheat sheets are practical for all of us who cannot remember the keyboard shortcuts of editors, command line arguments of Unix applications or basic rules for Bash scripting. Fortunately for us, there are some nice collections available:
* Cheat-sheets.org provides heat sheets, round-ups, quick reference cards, quick reference guides and quick reference sheets in one page.
* Scott Klarr has released a Linux-Unix cheat sheets - The ultimate collection
These two collections are a valuable aid for us who just cannot remember everything.
