rsync with (some) steroids – June 15, 2023.
I came up with a way of using rsync to be able to compare folders and list the files which actually have different contents, and in that case, which folder has the newest version. This means that, given two folders A/ and B/, all the files with differences are newer in (say) folder B/, I can just copy them over to folder A/, instead of doing individual merges. This is super useful to merge files that exist on both desktop and laptop, but that are not under version control.    #rsync #diff #merge #bash #script
