Perhaps your company is just switching to Linux, to save on costs. Or, maybe you’re starting University, and you have no idea how to get around the Linux Systems they’ve just installed. Or if you’re like me, you’re curious about how Linux works, and you have it installed at home.

Linux administrators cannot live by the GUI alone. That's why we've compiled the most essential Linux commands into this convenient guide. We designed this guide specifically for Linux managers and system administrators as a reference library of only the most useful utilities. By learning a few simple tools, command-line cowards can turn into scripting commandos, getting the most out of Linux by executing kernel and shell commands.

For tasks like controlling and monitoring the distro's underlying system, the command line remains indispensable. Here are some commands that will elevate you from a total newbie to an informed command line user.

As a Linux user you’ll come to learn and love certain commands. Remembering these commands is the toughest part. Some people use cheat-sheets some create scripts, and some just refer to website for their fix. Here I have posted the 25 top command line snippets.

In this post I will collect all commands which SHOULD NEVER be executed in Linux. Any of them will cause data loss or corruption, can freeze or hang up running system. NEVER RUN THESE COMMANDS IN LINUX BOX CLI! Even if somebody advises you in forum/im to do it.

Sometimes, if you’re following a tutorial on doing something on your Linux box and you’re trying to fix something, you’ll be asked to go to a terminal and type in some commands. Often, these commands need to be run as root, the administrator.

Running commands one right after the other can be a tedious way to get things done from the shell. What if there was a way to "chain" these commands together? Well fortunately Linux provides some ways to allow you to type in a bunch of commands at the prompt and run them as if it was one command.

Almost every Linux website seems to have a list of the "best command line commands". Sometimes they get them wrong. Here is a list of useful commands that I came up with by looking at my 'history' file.
