Cheat Sheet Roundup - Over 30 Cheatsheets for developers

Updated: February 10, 2022

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


Commercially Printed CheatSheets

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

Hi Everyone, thanks for the comments. I've been out of town this weekend, and I'll update the entry with your suggestions tomorrow.

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. W3Schools is a great quick and dirty (not terribly deep but broad enough for general use) site with many different topics:

And again.. not totally deep, but found some great cross-platform SQL code examples here:

Keep posting the great links!

The Oracle cheat sheet should be in the Commercial section since it is being sold by a company.

Very useful list. What about adding my new python cheat sheet?
by GreyFox on 01/03/2008 at 4:55:29 AM UTC
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:
