I am working on my Linux Ubuntu 14.04 from a long time and I understood that Linux Command line interface(CLI) is very powerful tool but ignored by many user. And If you are a newbie to Linux than CLI interface may be a ghost to you. So, I come up with this Blog which have some very Important Command in Linux / Unix.
