Download 21 Best Linux Command Cheat Sheets For Free

Last updated August 12, 2018 By Abhishek Prakash 7 Comments

This article provides you with a list of best Linux command line cheat sheets that you can download for free.

I’ll be honest with you. I am a cheat sheet fan. Especially when I am learning something new. It also helps me on topics which I know I’ll have to work on and off again.

Benefits of using Linux cheat sheets

When you learn something new, it’s normal that you won’t know all commands by heart. It comes by practice eventually, if you work on it continuously. Cheat sheets come handy for quick references in such circumstances.

You don’t have to memorize, or Google for repetitive commands each time. A little doc can be opened in a corner (either on your screen or on a printed paper) and you can have a quick glance at it.

I’ll count the cheat sheets as one of the productivity tools for Linux or for anything in general. You see, when you refer to your favorite cheat sheet time and again, you get familiar with it. You know which command is where and it helps save time.

You can always create your own cheat sheet or reference document. I always do it whatever tool/technology/product I work on. Remember, I shared my Vi cheat sheet in an earlier article.

This, of course, doesn’t mean that you’ll have to create all cheat sheets on your own. There are plenty of cheat sheets available on the internet for free on a wide variety of topics, you can search for them as you like.

However, for Linux users, I’ll take the burden of Googling and looking for the Linux command line cheat sheets.
