Screen is the best software used for full-screen window manager that multiplexes a physical terminal between several processes, typically interactive shells using only one SSH sesion or only one console.
Getting in
| |
|---|
| start a new screen session with session name | screen -S |
| list running sessions/screens | screen -ls |
| attach to a running session | screen -x |
| … to session with name | screen -r |
| the “ultimate attach” | screen -dRR (Attaches to a screen session. If the session is attached elsewhere, detaches that other display. If no session exists, creates one. If multiple sessions exist, uses the first one.) |
| detach a running session | screen -d |
Escape key
All screen commands are prefixed by an escape key, by default C-a (that’s Control-a, sometimes written ^a). To send a literal C-a to the programs in screen, use C-a a. This is useful when when working with screen within screen. For example C-a a n will move screen to a new window on the screen within screen.
