Like most of you, I’m a command line junkie. There are two advantages of using Linux command line instead of UI. First, you can automate lot of routine activities using command line and your productivity will increase drastically. Second, you’ll learn the internals of a particular feature (for example, configuring NIS) when you configure it using command line, instead of configuring it using UI.
While using command line intensively, following are the 4 Linux commands that I find practically useless. If you think they are useful, please explain a practical scenario under which you’ll use these commands with examples.
