Example: bash how to use screen

# Note, screen is useful for continuing processes (e.g. downloads) on a
#	remote server without having to stay logged in to the server

# Basic syntax:
screen # This starts a new screen. 

# After starting a long process, e.g., a download, detach with:
CTRL+a d # To detach from screen, press CTRL+a, release, then press d

# To view active screens:
screen -ls # The first numbers by each screen indicate the screen_number

# To resume active screen:
screen -r # If there is only one active screen
screen -r screen_number # If there are multiple active screens

# To close a screen after detaching:
screen -X -S screen_number quit 

# View all CTRL+ commands available in screen:
CTRL+a ?
