LinuxCommand.org: Midnight Commander

At the beginning of chapter 4 in TLCL there is a discussion of GUI-based file managers versus the traditional command line tools for file manipulation such as cp, mv, and rm. While many common file manipulations are easily done with a graphical file manager, the command line tools provide additional power and flexibility.

In this adventure we will look at Midnight Commander, a character-based directory browser and file manager that bridges the two worlds of the familiar graphical file manager and the common command line tools.

The design of Midnight Commander is based on a common concept in file managers: dual directory panes where the listings of two directories are shown at the same time. The idea is that files are moved or copied from the directory shown in one pane to the directory shown in the other. Midnight Commander can do this, and much, much more.
