Cheat Sheet Roundup - Over 30 Cheatsheets for developers

September 01, 2005

Lets face it, unless you have a photographic memory, no developer can remember all the different functions, options, tags, etc. that exist. Documentation can be cumbersome at times, thats why I like cheat sheets. They are quick references that feature the most commonly forgotten things on a specific topic. You can print them out and hang them on your wall, or just keep them handy in your bookmarks for quick reference.

I have rounded up over 30 cheatsheets that developers might find useful.

Web Development Cheat Sheets

Databases / SQL Cheat Sheets

Language Cheat Sheets

Version Control Cheat Sheets


Commercially Printed CheatSheets

Am I missing any good ones? Feel free to post any others in the comments.

This is very neato - to have all this in one location. However, I noticed the Oracle cheat sheet is a commercial download (costs $3.95). Wondering if it makes more sense to move it under the "Commercially printed" heading. Thanks for this compilation again.
Great list of cheat sheets! I'm sure I have a handful to add, but without checking my bookmarks, I wanted to toss this one into the fray.

Hi! I have been making cheat sheets for a few years now and using them effectively when learning new technologies! You might want to add a link to all of them, or a link to my page where I list all of them. I have created: * awk, * sed, * ed, * perl special variable, * perl pack/unpack and printf, * screen (terminal emulator), * bash emacs editing mode, and * bash vi editing mode cheat sheets. All of them are available for download in PDF format, some of them are in DOC (Microsoft Word), most of them are also available in TXT (ASCII), and a few latest in LaTeX. The URL of all the cheat sheets is: Sincerely, Peteris Krumins
