Screen - Virtual Terminals From Console
screen
screen [options] [command [args] ]
In their words: Provide ANSI/VT100 terminal emulation, making it possible to run multiple full-screen pseudo-terminals from one real terminal, and letting you manipulate and save your screen input and output, copy and paste between windows, etc.
In other words: multiple virtual terminals from one terminal (like a remote shell), with the ability to detach processes and leave them running even when you disconnect!
- Do more from one terminal connection
- Leave stuff running even if you detach or disconnect
- Handy for unreliable terminal connections
- Scroll back and see what you missed
Screen offers the ability to detach from a session and then attach to it at a later time. When detached from a session, the processes screen is managing continue to run. You can then re-attach to the session at a later time, and your terminals are still there, the way you left them.
Screen also maintains individual, searchable scrollback buffers for each of the windows it manages. Screen sends all entered text to the current window, with the exception of the command character. The default command character is Ctrl-A
