Launch a codeblock in "screen"

  • 772

I'm working on a script that downloads large files like installers, youtube video series or torrents. It's supposed to work on a Raspbian. So the main part has to be delt with in a screen session. Or else the user would have to keep the ssh connection active all the time.

It's also supposed to get it's input from a textfile containing multiple entries like:

http://youtube.com/BlaBla video ~/Videos
http://vlc-project.org/downloads/BlaBla file ~/Downloads
BlaBla.torrent torrent ~/Downloads

So the codeblock would be something like:

while read -r line; do
  # Code for simple file
  # Code for Video
  # Code for torrent
done < "$inputFile"

How do I execute the entire while loop in a screen session? Is this even possible?

Greetings and thanks in advance

  1. Screen man page mentions the following syntax:

    screen [ -options ] [ cmd [ args ] ]

    And this:

    In addition, new windows can be created by running a command like:

              screen emacs prog.c

    from a shell prompt within a previously created window. This will not run another copy of screen, but will instead supply the command name and its arguments to the window manager (specified in the $STY environment variable) who will use it to create the new window

    So put your codeblock into a script , and launch from a terminal it like so 

    screen myScript.sh
