Byobu is a program that makes using terminal multiplexers really easy. A terminal multiplexer is like a windowing system for console programs. Byobu uses tmux by default, but can be configured to use GNU screen too.
Byobu allows you have many console windows or programs running at the same time. You can detach from Byobu and later restore the session, with all your terminals and programs running intact. This is similar to hibernating and restarting an OS back.
- When opened, Byobu opens with your default shell. The bottom line of Byobu is like a taskbar and shows currently open windows (or tabs). You can see the default window (or tab) numbered 0 there.
- To open a new session named foo, use the command:
byobu -S foo
F2: Open a new window or tab. This means that a new shell session is opened in that window. This window is numbered 1, as seen at the bottom.
F4: Switch forward and backward between open windows.
Ctrl+A d: Detach from Byobu. Puts you back at the shell. All the windows and the shells inside them are still running. You get back to them whenever you want.
F8: Rename the current window. The name is shown at the bottom of each window. This is very useful to distinguish work you are doing in each window.
Ctrl + F2: Create a vertical split window
Shift + F2: Create a horizontal split window
Shift + F3or
Shift + F4: Switch forward and backward between split windows
F9: Change the settings using its inbuilt Curses GUI dialog.
Alt + F12: Toggle mouse support. More details in this post.
Shift + F12: Toggle function keys. This is useful when you want to use the function keys in a terminal application.
Tried with: Byobu 5.77 and Ubuntu 14.04
