Vifm is a ncurses based file manager with vi like keybindings, which also borrows some useful ideas from mutt.

ncurses, or new curses is a programming library providing an application programming interface that allows programmers to write text-based user interfaces in a terminal-independent manner. Vifm is easy to use, but more so for those used to using the keyboard. Those not familiar will like the tips that are always displayed in the lower left status window.

There are two ways to viewing and process file lists; tree-view and directory-comparison. Because of the numerous features that you can discover, we've opted to shorten the review and copy their list of features here:

ranges in command-line commands
user defined commands (support ranges)
registers
directory tree comparison
operation undoing/redoing
FUSE file systems support
multiple files renaming (also known as "bulk renaming" or "batch renaming")
color schemes, which can also be applied to specific sub-trees
colorization of files according to their type and/or name
