Most computer users today are spoiled by the richness of the graphical user interfaces or GUI. In Linux, we have dozens of desktop environments that compete against each other for dominance. Right now, GNOME seems to be winning. However, accessing servers remotely using the same desktop environment puts a heavy demand on the network connection. This is one of the reasons why mastering the command-line interface (CLI) is an added ammo in a 's arsenal. Frankly, it is a must-have in my book.
Anyway, using the CLI does not necessarily have to be too tedious specially when dealing with file management, e.g. moving files from one subdirectory to another, etc. The task is made simpler by a file manager named Midnight Commander (after the popular DOS utility, Norton Commander).
Installation is as simple as invoking "sudo apt-get install mc". It should not take that long to download and install. PolishLinux.org has a short walk-through of what you can do with Midnight Commander.
What do you think? DO you know of a simpler CLI tool?
