I saw this on Digg’s upcoming stories today: Totally complete sources.list for Ubuntu Feisty Fawn, and felt a chill of terror. Visions of masses of users new to Ubuntu (and Linux in general), downloading this sources.list and using it, watching their computers melt, and blaming Linux overwhelmed my poor little brain.

LCoTD: Basic File Operations
Apr 19
One of the first things you’ll need to do on a Linux system is manipulate files: copying, renaming, deleting, and so forth. There are a number of commands to perform these actions, and they are: ls (list files in a directory), cp (Copy a file), mv (rename (“move”) a file), rm (Delete (“remove”) a file), and ln (Create links (alternative names) to a file). In today’s installment, we will cover all of these commands

In my last Linux Command of the Day article, I covered how to install any software package in Linux. Shortly after, I found this post over at darxr.net. What a perfect chance to put your new skills to the test! (Yes, I know The GIMP is mentioned, and I previously said that it wasn’t enough for my needs. However, it is still a very powerful image editing tool that I use when I don’t need all the features of Photoshop)

OK, so the thing that kept me from using Linux for the longest time was the fact that it had little to no software availability. Or so I thought. While it remains true that I use Photoshop and 3D Studio MAX above all else, and will never fully switch to Linux (sorry, The GIMP just doesn’t cut it for me), there is a wealth of software available written and maintained by the open source community. This Lesson will teach you how to install it.

Today I’ll be covering job control. What exactly is job control, you ask? No, it isn’t resisting the urge to give your boss the finger every morning at 9:15am. All Linux shells have job control: the ability to run programs in the background (multitasking behind the scenes) and foreground (running as the active process at your shell prompt). A job is simply the shell’s unit of work. When you run a command interactively, your current shell tracks it as a job. When the command completes, the associated job disappears. Jobs are at a higher level than Linux processes; the Linux operating system knows nothing about them. They are merely constructs of the shell. Some important vocabulary about job control follow.

This one’s a real doozie. In today’s Linux Command of the Day, I’ll be covering Input/Output redirection, pipes, combining commands, quoting, escaping, command-line editing, command history, and filename completion. I know it sounds like a lot, but it’s all really quite simple, and not too much to take in! But that doesn’t mean it isn’t essential to know- in fact, quite the opposite! This information could save your life one day (ok, maybe I’m being a bit dramatic for 99.98% of my readers, but for that 0.02%, you’ll be glad you read this!)

Today, I’ll be covering the Linux “Shell”. In addition, I’ll be touching on the commands, who and type but the focus of this article is learning how the shell works, and by extension, what you are actually doing when you enter commands.
