my screenrc preferences
$ cd ~ $ git clone https://github.com/nbla/screenrc.git $ ln -s screenrc/.screenrc .screenrc
the one-liner (same commands as above, just one one easy copy line):
cd ~; git clone https://github.com/nbla/screenrc.git; ln -s screenrc/.screenrc .screenrc; echo "alias screenx='screen -RaAd -S x'" >> ~/.bashrc; source ~/.bashrc
