Mosh is a remote terminal application that allows roaming, supports intermittent connectivity, and provides intelligent local echo and line editing of user keystrokes. It is a replacement for interactive SSH terminals, offering more robust and responsive performance, especially over Wi-Fi, cellular, and long-distance links. Mosh is free software, available for various operating systems, including GNU/Linux, BSD, macOS, and iOS. The application automatically roams as the user moves between internet connections, allowing for seamless transitions between different networks.
