That code was suggested by someone.

du gives file sizes in "blocks", but that's certainly more precise than megabytes.

Here having multiple commands between while and do is an alternative to the true/break.
The last exit status (before the do) counts.
Code:
while
    sleep 5
    new=$(du -s /home/andy/Downloads/myfile.iso)
    [ "$old" != "$new" ] 
do
    old=$new
    xdotool getactivewindow key Ctrl
done

My own tuppence worth on this:
  • As this is in the Ubuntu sub-forum, ps has a -b (size in bytes) option;
  • If you want the size of a file in bytes, surely the most accessible (and therefore most portable) option is to use wc -c
  • As you are using bash, surely the [[ ... ]] construct is better as you don't have to quote variables;
  • If using numeric comparison in bash, using the (( ... )) construct is more readable.
