Linux – How switch between screen inside screen

You can run this: ssh -t hostname screen -r 3453 to reconnect. If you want to do it in a loop I use the following in a script.

while true; do
    ssh -t -o BatchMode=yes eeepc-rsi "screen -r 3453"
    sleep 2
done

This works best if you have ssh-keys setup so you can login without typing in your password. I'd also recommend that you look at tmux, a more modern implementation of screen. I actually use the above script with screen. You probably also want to use a named screen session rather than just using the pid like you do in your example.

For the first and third points, try setting TERM while you're using screen to the same things it is when you're not (or if it's already the same, try setting it to "screen").

Edit:

To have vim exit so it shows the contents of the screen before you started it while running under screen, add altscreen to your ~/.screenrc file.

Edit 2:

To make underlined text show in color add this to your ~/.screenrc file:

attrcolor u "-u R"

The "R" stands for bright red. Lowercase would be normal. "B" is blue, etc.

Edit 3:

To stop the extraneous underlining, add this to your ~/.screenrc file:

attrcolor d -d

The first "d" stands for default. The "-d" means remove the "dim" attribute.
