Everyone knows what a Linux shell is -- you open up a Linux terminal window (such as Konsole or xterm), type in some commands, and there you are, using your Linux shell. Write your commands to a file, make it executable, run it, and you're a shell programmer. But did you know that there are different shells that you can use, and that each shell operates in a slightly different way?

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.

"Have you ever wondered how it could be that Lisp is so powerful, and yet C is so much more successful and ubiquitous? How is it that so many brilliant coders know Lisp, and yet we so rarely hear from any of them other than Paul Graham? This is a great article that tries to explain it: the bipolar Lisp programmer." -- «So what's the problem with Lisp?

Source code is the set of instructions that some programmer wrote for your electronic device. That programmer may very well have been me, and I may have told that device to despise you and to do anything in its power to make your life hell. Keeping that in mind, take a long, hard look at your laptop. Do you have any idea what that thing is thinking right now?

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.

The most complete and updated list of commands on linux by LinuxGuide.it - over 350 commands!

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.

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.

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.
