Command line tricks for smart geeks
Everyone knows the answer to the question of life, the universe and everything is "42", but for the first time we can reveal the question. It is this: how many command-line tricks must a man memorise? You see, graphical user interfaces are all well and good, but when you want to get real work done it's time to switch to the terminal. And so, we squeezed our brain cells, dug through dusty piles of old issues of Linux Format, and sat reflecting quietly over many a pint of ale, all with the goal of bringing you this: 42 awesome new command line tricks we think you ought to commit to memory.

How To Configure Remote Access To Your Ubuntu Desktop Version 1.0 Author: Falko Timme <ft [at] falkotimme [dot] com> Last edited 01/23/2008 This guide explains how you can enable a remote desktop on an Ubuntu desktop so that you can access and control it remotely. This makes sense for example if you have customers that are not very tech-savvy. If they have a problem, you can log in to their desktops without the need to drive to their location. I will also show how to access the remote Ubuntu desktop from a Windows XP client and an Ubuntu client. I do not issue any guarantee that this will work for you! 1 Preliminary Note I have tested this on an Ubuntu 7.10 (Gutsy Gibbon) desktop. 2 Enabling The Remote Desktop We don't have to install anything to enable the remote desktop on Ubuntu. (JavaScript must be enabled in your browser to view the large image as an image overlay.)

8 Useful and Interesting Bash Prompts Many people don’t think of their command prompt as a particularly useful thing, or even pay it much attention. To me, this is a bit of a shame, as a useful prompt can change the way you use the command line. Well I’ve scoured the Interwebs looking for the best, most useful, or sometimes most amusing bash prompts. Note – to use any of these prompts, you can copy & paste the “PS1=” line directly into your terminal. 1. This prompt is probably the most amusing one on the list, but remains useful. Example: Code: 2.Change color on bad command Here’s one of my favorites. 3. If you’re the type who wants to pack your prompt full of information, then here’s the one for you. 4. There’s nothing particularly fancy about this prompt, other than the good use of color to separate the different pieces of information. 5. This one’s a nice, clean, minimal 2-line prompt (plus a blank line at the top). Code: 6. Another nifty 2-liner, but this one’s got some info we haven’t used before. 7. 8.

4 Strange And Disturbing Linux Distros You Probably Won’t Be Installing Linux is the operating system of choice for those who decide to go their own way. The open source model means the building blocks are there for you if you decide that you need your very own operating system. This has resulted in more Linux distros than you could ever imagine.

Ubuntu Satanic Edition has received numerous complaints and messages of discouragement.
