Rodent – Advanced User file manager for Linux systems

Rodent is fast, small and powerful file manager for the GNU operating system (but it also works in BSD). That's one way to look at it. Another way is to call it a graphic shell (that's probably more accurate).

Rodent wastes no space on menus or function buttons (display real estate is too valuable).
All functionality is available through popup menu or keyboard action.
Popup menu is context sensitive.
Full lpterminal is available from keyboard.
Functionality is extendible via plugin tecnology.

The following programs are included with Rodent:

-- fgr
-- rodent-diff
-- rodent-root
-- rodent-mime
-- rodent-desk
-- rodent

Install rodent on ubuntu

You need to download deb package from here  once you have deb package you can install by double clicking on it
