Once I was using rsync to copy some large files from a cloud to my local machine. So right after I started it, I went out for some coffee and when I came back it was not done. And to my horror I forgot to use --progress. For people who don't know what it does is , it only shows you how much copying is done. So now after about 45 mins of copying done , I had to stop it start all over again with --progress so that I can see the progress as it completed. 🤔
