If for whatever reason you stop using a certain service in your Ubuntu install and would like to disable automatic restarting for it upon system reboot, all it takes to do it is just one command line.

If you want to quickly create a new user account in your Unix OS, it ca be done with just one line

Adding new user accounts in Unix

To create a basic Unix user account with default settings, you need to know only one thing: the username.

The reason I say it as one word is because username (quite often referred to as "login") is not the actual name of the new person gaining access to your Unix system, but rather a single keyword uniquely identifying this user in your system. Most often, usernames are derived from real names of users – jsmith, johns or smithj for John Smith, just to give you a few examples.

The simplest way to add a new user to your system is to do run a command like this:

ubuntu# useradd jsmith

I've just integrated a new section: Unix Commands. The long-term plan is to have a categorized list of commands with most common usage documented in my typical easy-to-follow examples.

So far, there's not much, but I will referer to this section a lot in my future posts and its pages will have more examples for a particular Unix command compared to the original Unix Tutorial post where such a command is mentioned.

Have a look for yourself:

• Unix Commands – the main index
• Basic Unix commands – like it says, they really are basic. If you can think of something else which should be part of it, let me know
• Advanced Unix commands – to Unix gurus they'll seem basic as well, but my only guidance so far was that commands there will be the ones you don't have to use on a daily basis. As I add more pages, this section will most likely become something like "Most common Unix commands" and a set of really advanced commands will be added.

Let me know what you all think, and if there are some immediate candidates for any of the section – let me know and I'll add them to my list!

Right on time, next release of Ubuntu Linux has arrived. Ubuntu 8.10, codenamed Intrepid Ibex, is officially out.

CodeWeavers are giving their award-winning CrossOver software for free.

What is CrossOver?

CrossOver is a tweaked and polished, proprietary version of Wine – an implementation of Windows API for Unix. Simply put, it's a software which allows you to run Windows applications on your Unix system. Wine, especially since the 1.0 release, is quite a pleasant and reliable way of running Windows software on your Unix desktop, but CrossOver is known for putting many more tweaks on top of the features implemented in Wine, mostly to make popular office packages (Microsoft Office) and games work even better in emulated environment.

CrossOver Pro For Free

For one day only, October 28th 2008, you can go to the CodeWeavers website to request your free registration key for the professional version of their CrossOver software suite – either for Linux or Mac. These are fully functional serial keys for the pro version, technical support included.

The trick is that you need to have this key activated as soon as possible! Originally, you were only given time until midnight, but it is now promised that you'll get another 48hours to activate your key, although free registration keys will stop after 23:59 PM Central Standard Time.

Wait no more – the main CodeWeavers website is already down due to traffic, but Free CrossOver Pro registration form is still available!

For all the new visitors of this blog, I've just created a Using Unix Tutorial page which is linked from the sidebar.

Please feel free to have a look and let me know if there's any more introductory information I can add to make it even easier for you to find and get exactly what you came looking.

Each process in Unix has its own set of environment variables. They're called environment variables because the default set of such variables consists mostly of session-wide variables used for configuration purposes.

From the point of a Unix shell though, environment variables can be accessed the same way as any other variable.

Every week there's a few announcements or articles which I find particularly interesting, and so I've decided to share them with you. I'm not a Unix guru (yet), but if any of the listed materials require further explanation – do feel free to ask and I'll be glad to help.
