screen
Entry published nov 13 2005
I discovered the incredibly useful unix program screen just recently. It allows multiple terminal sessions running at once and it provides easy access for switching between sessions. To run the command type:
screen
Once screen is running you can do Control-AC to create a new window and use Control-A followed by a number to switch to that session number. And the best I’ve saved for last, if you close your terminal session and want to get back to the screen you were working on, just type:
screen -r
Magically, screen will come to life just as you left it, which makes it great for running on remote servers.
