Linux Commands Cheat Sheet
Linux cheat sheet offers a set of commands that you can use for quick reference. Remembering every command is not possible and it can be quite daunting for a novice user. The good news is that you don’t need to remember each command. Only a very small subset of those commands are used on a day-to-day basis.
One of the main advantages of a command line interface is that it allows users to type in commands that can produce immediate results. Those familiar with command-lines find this method quick and simple.
