FileRunner is a two-pane file manager for Unix. It is simple and efficient and has a built-in FTP/SFTP/adb client. It does a reasonable (and improving) job on Windows systems. It features a simple and powerful interface, history and Hotlist (bookmarks), a recursive directory menu of the entire filesystem tree, browsing FTP, sFTP, and adb directories as easily as normal directories, asynchronous file transfers, cached directory listings, asynchronous file operations, built-in command shell windows synchronized with file panels, extensibility by adding your own command buttons, and user-defined file pattern/actions.
pfm is a terminal-based file manager written in Perl. All pfm commands can be invoked with one- or two-key commands. It features integration with version control systems, use of the ReadLine library for friendly command line editing, support for executing user-defined commands, colored filenames according to extension or type, a single-file and multiple-file mode, and bookmarks for directories.
