While downloading in progress, you can press “Ctrl-A” and “d“. You will not see anything when you press those buttons. The output will be like this:
[detached from 5561.pts-0.mint] pungki@mint ~ $
Re-attach the screen
After you detach the screen, let say you are disconnecting your SSH session and going home. In your home, you start to SSH again to your server and you want to see the progress of your download process. To do that, you need to restore the screen. You can run this command:
pungki@mint ~ $ screen -r
