APTonCD : Create local removable repository of downloaded packages

I have a really slow internet connection in the university i am studying in so for installing applications i have to usually keep my laptop powered on for considerable period of time this almost makes it impossible for me to remove my existing Ubuntu installation and do fresh new installation again as i risk losing all my downloaded packages.

APTonCD is a tool that can help you precisely in such situations . Whenever you install applications via synaptic/apt-get/aptitude the corresponding Debian files are downloaded and stored (/var/cache/apt/archives) then they are installed on your system . APTonCD helps you create local repositories of these downloaded package files along with all its dependencies on a CD/DVD so that you could install these application on any computer whether internet connection is available or not using apt-get tool.

APTonCD is availble in Ubuntu official repositories and could be installed easily by issuing the following command in the terminal window :
sudo ap…

Transforming your Ubuntu 8.04 Desktop to look like Mac OS X

Please read THIS, the link points to an Updated Article for Ubuntu 11.04.

MAC OS has been traditionally known for their impressive graphical interface and stability. Now even though i have been an avid Linux follower over the past 9 years I have been using Linux still i find my self attracted to MAC OS .Now even though these days it's possible to run Hackintosh on normal Intel hardware but it's not stable and well there are hardware compatibility issues . So well other alternative to using MAC OS is either to purchase MAC hardware(which would be naturally expensive) and run full fledged MAC OS or you could tweak and customize your Ubuntu desktop to look more like MAC OS X .

In this tutorial i describe step by step how to make your Ubuntu 8.04 desktop look more like MAC OS X Leopard :) .

Displaying sorted list(size wise) of Files/Folder on Linux

Even though i have a 120 GB HDD on my laptop and have dedicated a significant portion of hard disk space to Ubuntu still somehow every three or four months i run out of disk space . Also i am particularly bad at organizing stuff and well files are cluttered over my entire file system this makes tracking large files i don't need very difficult . Lots of application create a number of temporary files and these files also take significant amount of disk space and could be hard to track down if they are not created in /tmp .


The command I am discussing below helps you solve precisely this problem by giving you an ordered list (ordered in terms of size) of files and folders taking up space in your computer thus helping you find files/folder which are taking up significant amount of space :

du -sm *


Above command would display all the files and folder as well as their size as a list, however this is not a ordered list . To order the list we would need to pipe (that is send output…

Replacing Nautilus with quicker and faster PCMan File Manager in Ubuntu 8.04

Nautilus is the default file manager used in Gnome by most of the Linux distributions, now even though nautilus is extremely user friendly and has wide array of features(including ability to extend it's feature set with scripts and extensions) . All these features does make nautilus bit resource hungry especially if you are using older machine. In this article i discuss PCMan File Manger which is a lightweight alternative to nautilus and how to set various menus in Ubuntu to using PCMan File manager instead of using nautilus.

PCMan File Manager is extremely small and fast file manager that supports Tabbed Browsing. It is not as feature rich as Nautilus which probably helps it by making it much faster compared to nautilus which take a significant amount of time to load , however it does the job of file manager well . It uses multi threading to load large directories quickly and even shows thumbnails of images. It has been created using GTK2 Libraries and it's website claims it c…
