Linux Command List

In this article, i would be giving out a list of command list which are very commonly used on a day to day basis. Keep in mind that the command list given here is not the "LAW" but just a list of commands that i feel would be useful for users making a transition from Windows or any other platform into Linux. There also many be others which i would have missed out and are equally important.
