"Byobu - Terminal Multiplexer"


byobu Byobu is a GPLv3 open source text-based window manager and terminal multiplexer. Byobu includes an enhanced profiles, convenient keybindings, configuration utilities, and toggle-able system status notifications for both the GNU Screen window manager and the more modern Tmux terminal multiplexer.

The key benefits are:

It provides easier to remember keybinding to Screen/Tmux.

Terminal sharing is easily done with just two terminal sessions ( same user account ) running byobu.

Automatic resumption of terminal session if remote is reconnected

Byobu defaults to launching tmux.

SCROLLBACK, COPY, PASTE MODES Each window in Byobu has up to 10,000 lines of scrollback history, which you can enter and navigate using the alt-pgup and alt-pgdn keys. Exit this scrollback mode by hitting enter. You can also easily copy and paste text from scrollback mode. To do so, enter scrollback using alt-pgup or alt-pgdn, press the spacebar to start highlighting text, use up/down/left/right/pgup/pgdn to select the text, and press enter to copy the text. You can then paste the text using alt-insert or ctrl-a-].
