By specifying ls -ltr, I assume that you are trying to move the oldest file each time you invoke this script. Is the intent to move only the oldest files in that directory and quit selecting files when the next oldest file would create a combined size >= 3 GB? Or is the intent to move the oldest file and select more files until you get as close as possible to 3GB even if some of the selected files are not the oldest files in the directory?

By 3 GB do you mean 3 * 1000 * 1000 * 1000, or do you mean 3 * 1024 * 1024 * 1024?
