Does running the command xdotool getactivewindow key Ctrl cause the size of /home/andy/Downloads/myfile.iso to change?

Note that MadeInGermany is correct about du -s reporting file sizes as a number of blocks (512-byte blocks if the version of du on your version of Ubuntu adheres to the standards; but quite likely on most versions of Linux systems you'll get counts of a larger sized block). If you want to detect small increments of change, please do not use wc -c pathname as suggested by apmcd47; that will increase the CPU an IO load on your system significantly if you are downloading a large file. Using ls -n pathname would be a much better choice. It will report changes in file size to the number of bytes in the file and only has to do a stat() on the file to get its size; using wc -c pathname is usually implemented by wc opening, reading, and counting every byte in pathname. (Note that ls -n output is like ls -l output except it prints the file owner's user ID and file group's group ID instead of looking up and printing the file owner's user name and file group's group name; therefore, it is slightly faster and uses fewer system resources to get the job done. If you were using a UNIX system instead of a Linux system, I'd suggest using ls -og which avoids printing user and group names or IDs completely.)
Running xdotool getactivewindow key Ctrl does not do anything.

OK. So if running xdotool getactivewindow key Ctrl does not do anything, why are you running it every five seconds until the size of /home/andy/Downloads/myfile.iso stops changing?

That code was suggested by someone.
