Terminal multiplexer
open-in-new
<p>A terminal multiplexer is a <a href="/facts/Software_application/YQuj7Kog">software application</a> that can be used to <a href="/facts/Multiplexing/YE7hK8cw">multiplex</a> several separate <a href="/facts/Pseudoterminal/CV9rjfhz">pseudoterminal</a>-based <a href="/facts/Login_session/plmwnSNU">login sessions</a> inside a single terminal display, <a href="/facts/Terminal_emulator/yNfevBJd">terminal emulator</a> window, PC/workstation <a href="/facts/System_console/FhWph34D">system console</a>, or remote <a href="/facts/Login_session/plmwnSNU">login session</a>, or to detach and reattach sessions from a terminal. It is useful for dealing with multiple programs from a <a href="/facts/Command_line_interface/R9JpGmXQ">command line interface</a>, and for separating programs from the session of the <a href="/facts/Unix_shell/2G4T2Fb9">Unix shell</a> that started the program, particularly so a remote process continues running even when the user is disconnected. </p>
