CliFM is a Command Line Interface File Manager: all input and interaction is performed via commands. This is its main feature and strength. Unlike most terminal file managers out there, indeed, CliFM replaces the traditional TUI interface also known as curses or text-menu based interface by a command-line interface (CLI),1 also known as REPL.2 If working with the command-line, your workflow is not affected at all, but just enriched with file management functionalities: automatic files listing, files selection, bookmarks, tags, directory jumper, directory and commands history, auto-cd and auto-open, bulk rename, TAB completion, autosuggestions, and a trash system, among other features. In this sense, CliFM is certainly a file manager, but also a shell extension.
