Midnight Commander

GNU Midnight Commander, known as mc, is a free clone of the DOS Tool Norton Commander (→two panels) and is one of the most famous console programs for Linux. Over a VFS it's also possible to access archives ans network servers easily.

For Linux beginners, if you have used a similar tool under DOS, Windows or OS/2, it helps with many tasks. The biggest advantage is the versatility: mouse support (GPM), integrated FTP Client, unpack different types of archives and packages (of course the programs need to be installed before) tar.gz, bzip, zip, rar, rpm, deb, ... . And yes, many operations are faster in the console using commands. But with mc it's easier, e.g. copying, deleting, ... of files which can be difficult to filter. And last but not least, the integrated editor with syntax support (for almost any language) and simple interface is a big help for new users (which might think vi is a French cheese).

As it is a console program with function keys, many operations will be performed quickly after a short learning period. Much faster as from the console with commands or with a GUI. mc is much better as GUI file managers, especially regarding speed.

The Midnight Commander on the Dreambox can be "stripped" and might have limited functions available. It's recommended to learn this tool to perform quickly many tasks without installing any software on a PC before.

Start Midnight Commander

Connect via Telnet or SSH with the Dreambox and enter following command in the console (Terminal):

mc

The Midnight Commander will be started, and looks like the image in this article...
