sFTP is a screen-oriented FTP client, based on the curses library. It establishes a session to the FTP server, and displays the contents of the directory on the FTP server in a window. Another window shows the contents of the current directory, locally. You can transfer files simply by moving the cursor in the scrollable list until it is on top of the file, then hitting enter.
