I am an ancient user of Gnu Screen. I am the one who will suggest new users use these better tools for servers. Gnu Screen is an excellent tool, but It is tough to configure and learn.
Recently I found a replacement. The Tmux!
Tmux is very easy to use. The best part is the shortcuts. 🙂
To install it in mac do
$ brew install tmux
$ sudo apt-get install tmux
You can put your setting in
# set -g default-terminal "xterm-color" set -g terminal-overrides 'xterm*:smcup@:rmcup@'
This should be enough to get you started. Google for Tmux cheat sheet to know popular shortcuts. Here is one of them. http://cheat.errtheblog.com/s/tmux
