If you spend any length of time in the shell, chances are you've typed the same commands over and over. It's usually not anything you can necessarily script as the commands may vary slightly on each invocation, but there are certain commands that can be used often with a little variation on each call.

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.

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.

While a few commands, such as 'cd' are built directly into bash; many of the most important commands come from coreutils, a GNU package containing over a hundred commands.

Not long ago, I have listed here some useful Linux terminal commands and those that I described as deadly. This time, I decided to gather some commands that I think have no practical use. I know it sounds interesting but you may disagree with me on some of the commands that I'll list here as you may find a few of them useful.

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.

Before, I have posted here a few basic Linux terminal commands that I think are essential for newbies to know. I've also shared some deadly ones that should be avoided at all costs.

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.

When you are new to Linux you often seek to get help from others and almost most of the advices you get will be in the form of some commands such as ps, top, modprobe, lspci etc. Be careful when you run these commands as some Anti-Linux a**holes try to fool new Linux users in the name of tips and tutorials.If after following such command(s), you lose all your files, no one is to be blamed but you.
