Hello, GNU/Linux knowledge seekers,

I assume that you have got accustomed to installing, using ubuntu comfortably. The more you get knowledge about UNIX comamnds, the easier will be the operation of ubuntu. You will have to add some repositories if you want to add some softwares. Most of the people would add repositories in the graphical way, i.e., they would open ubuntu software center, then they would click on Edit -> Software Sources. If ubuntu demands for a password, then they would enter it. Then Software Sources would open. Then they would click on the tab named as Other Softwares. After that, they would click on +Add. Then another window would open. And the users will enter the repository name in the text field, and will click on +Add source. Then ubuntu software center would refresh it self so that the software which is linked to that repositiry would appear in software center.

Uff!!! so many steps! If you try all these in non-graphical way, then it would be too fast and will save the time. The standard command to add a repository to ubuntu software sources is as follows. So open termainal by pressing ctrl+alt+t.
