Windows XP doesn’t come with a utility that allows you to see what files/folders are taking up the most room on your hard drive.  Don’t fret: sure there are programs out there you can download and install to do the job, but did you know you don’t have to actually install any software on Windows to actually find out what’s hogging all of your disk space? Well, it’s really easy as long as you have a Linux Live CD lying around. In this tutorial, we will be using Linux Mint 12 since it’s very popular right now in the tech world it’s currently leading the pack according to Distrowatch. Baobab, more commonly known as Disk Usage Analyzer, is part of gnome-utils and it is just an awesome graphical disk usage analyzer. You’ll find it on just about all Linux distros running the GNOME desktop environment.

Linux Mint screenshotStep 1:

Fire up your Linux Live CD running a GNOME desktop environment, in this example you will see we are using Linux Mint 12. Then, navigate to: Applications | Accessories | Disk Usage Analyzer

Step 2:

Here you will see Disk Usage Analyzer, and since we are in a Live environment, it defaults to the Live CD environment as shown on the right. Click on the green “Scan a folder” icon.

 

Choose filesystemStep 3:

Choose your hard drive listed on the left side. It will be the item that mostly likely has a size listed in GigaBytes – In this case it’s my 39 GB Filesystem. Then click Open in the bottom-right corner. If you have multiple hard drives they will be listed here as well.

 

Windows filesystem displayedStep 4:

After the filesystem is scanned, it displays the top folders on the left in list form, also graphically on the right side, showing color-coded comparisons of each folder. You can also view it as a treemap chart if you choose.

 

 

Hopefully this tutorial will give you some ideas on how even if you don’t use Linux as your daily operating system, you can take take advantage of some of the unique capabilities you gain by at least having a little Linux at your disposal!

Learn How To Install Software In Linux and Unix Distros

By Eddison Sherry

many Linux distrosFor a Linux enthusiast there are a variety of distributions (distros) or otherwise called flavors available in the internet. These distros vary mostly in the package management system they use to install software and also in their philosophy. Although the basis is same, it is the differences in handling the power that the kernel (Core program of the operating system) delivers that makes them distinct from each other. A newbie can easily get confused with the concepts in Linux, thanks to Microsoft which serves as an introductory course to using a computer the way you want it. In this article we will check what all options are catered for a normal user in installing software.

Red Hat LinuxMainly the distros can be categorized on the basis of package management system into three viz, .rpm based (redhat package manager), .deb based and the source based. The first category.rpm has its basis on Red Hat operating system or extensive usage of their code. openSUSE, fedora, Mandriva are a few to mention in this class.

Debian Linux

The next class is.deb or Debian based distros. Multitude of distros are available in this too most prominent one being Ubuntu.

 

ThGentoo Linuxe third category uses the source code for its primary operations Gentoo linux being one among them. Many distros provide additional front end programs to make it easier for the user to add or remove libraries or software’s to the system which may be either GUI based or command based.

yum package managerNow we will have a look at a few conceptually best package managers used by the distros. Red Hat has Yum (Yellowdog Updater Modified) package manager for the convenience of the user. It was originally developed to manage Red Hat Linux systems at Duke University’s Physics department.

Synaptic Package ManagerUbuntu has the synaptic package manager which uses the underlying apt(Advanced Packaging Tool) to gather and install software. Gentoo uses portage as its software installer but is a bit different in behavior from other package managers in that it deals with source code and compiles and installs for the specific machine on which it is running. These package managers install software from any recorded media like CD or DVD or from internet servers called repositories maintained by distributions and communities associated with its development. All these software managers resolve dependencies between packages while installing a software or library. Dependencies arise when a software might be compatible with a particular implementation of a library file where as another software we are trying to install might need a different underlying implementation of the same concept. When the two such conflicting software’s needs to coexist then the library file preferences need to be sorted out. Software’s usually depend on many libraries and hence the automatic management of dependencies is a welcome move as far as the huge Linux users community across the globe is considered as it would alleviate the problems in managing the system.

There is ample scope if you are a nerd or a geek to have your own way of tweaking the system and this is what fancies the computer addicts to use this powerful operating system. To conclude let us assume that the competition in the field gives rise to wonderful Linux based operating systems easily manageable and gives a new dimension to computing capabilities of the new generation.

Eddison Sherry had been working in Linux and other Unix flavours for long years. He had been writing blogs and article on the Linux Storage, Linux Commands and Linux Server Administration. If you are working on Linux or Unix Server its best to have a look on his blogs at Linux Technical Forum.

New User’s Look at Linux

By Roy Revil

Without getting too technical Linux is a form of operating system that is open source and free to the public. It is primarily based off the Unix operating system architecture. Linux was designed by Linus Torvalds back in the 80′s. For years the operating system was used mainly in a command line form and was not very user friendly at all. In fact, unless you were well versed in the operating system, it was hard for a beginner to do even the simplest of tasks like typing a document. Linux and Unix are widely used today for servers with specific tasks like NAS (Network Area Storage) or Website hosting. After a while they developed the UI (User Interface) more and more to accommodate even new computer users. With the code being open source, it leaves endless possibilities for countless people/vendors to come up with their own version of Linux. Because Linux is open source that means it is free to everyone and developed under the GNU (General Public License). Free is always better right? I am not sure about you, but I always believed that you get what you pay for. This doesn’t mean Linux is useless because it is free but instead there will be troubles and workarounds needed to use it on an everyday basis.

What is Linux?

Linux BrowserDistros: Fedora is one version or “distro” of Linux that leans more towards the new or general user. Fedora is made by the makers of Red Hat. It was one of the first Linux versions I happened to play around with. It has a neat nice design and catchy user interface which appeals to new users but can also make you the object of some nerdy jokes. A friend of mine, that is pretty decent with Linux, once told me that Fedora id like Linux for n00bs. I would probably agree as most leet Linux users don’t even use the GUI (Graphical User Interface) but instead just do everything through the terminal. The terminal is a way of doing tasks by way of command line. Although it looks cool to watch someone who knows their stuff navigate through the terminal, it is really no fun at all.

People like easy and they like things that look pretty. Fedora delivers on this in a pretty efficient manner. Fedora, along with other versions like Ubuntu or PCLinux OS, can be run either installed or run as a Live CD. Live CD’s are pretty cool because the entire OS run off the CD and makes no changes to the PC. This is great to test out different distros without having to reinstall every time. I worked at a place once where our primary PC’s hard drive died. We threw in a Linux Live CD and were up and running for most tasks that we needed to do.

Compatibility: Compatibility can be an issue sometimes when using Linux, however, most compatibility issues can be handled pretty easily. One of the best things Microsoft did with Windows 7 was increase the hardware compatibility. A lot of devices can just be plugged in and Windows will find the drivers for you. Linux however is not as developed in this regard and installing some things can be quite a pain. Now there are always exceptions to the rule. For instance, the last time I installed Ubuntu and Fedora on my laptop neither one installed the driver for my wireless card. After plugging the laptop directly into the internet and doing an update the card was found and installed properly.

I haven’t looked too far into this to see how many devices it actually works with it but given the current situation Linux may be more on the ball then I may think. Software compatibility is another story altogether. Just as the operating system is free, some of the software is also free. There are lots open source/free software out there that can do most things that software for Windows can do. Open Office is an open source office program that, in most ways, can be compatible with Microsoft Office. If you need an email client like outlook, Linux has programs like Evolution. Not everything is going to be 100% compatible but neither is the compatibility between Windows and Mac.

Why isn’t it more popular? Well, as I stated above, it is not the easiest thing to use or navigate. Not to mention the GUI development hasn’t been the greatest until lately. There have been a few cases where EEE PC’s (netbook like laptops) were sold with a Linux OS instead of Windows. This was to make the PC cheaper and smaller in size by not needing much hard drive space to run efficiently. They were not very popular because the normal consumer didn’t quite understand how to use Linux and in order to make it compatible with their other Windows based PCs they had to use workarounds or change the way they use the PC.

Test it out! I would like to encourage anyone to give Linux a try. Using the Live CDs there is really no harm in trying. Personally, I would love to see Linux take off and more widely used among the average PC user and not just server administrators. Next time I purchase a laptop or PC I would like to be given the choice of Windows, Mac, or various Linux distros.
