Okay, so using the cp command with the -Rn switch is convenient for say copying my Music folder from my home directory to an external hard drive or the SD card for my portable Media player when the destination already has an older copy without needing to copy everything already present in the old copy, manually determining what's been added and copying manually, or dealing with a bunch of prompts. It also allows an aborted copy to more or less be resumed from where it left off. This method is simple enough to not require scripting or complex command syntax, but it does have a few downsides: 1. It won't overwrite corrupted files left by an interrupted copy, and such files are too rare for manual searching. 2. Files that have been altered don't get copied. unless they've changed filename. Not a big issue for copying my Music folder since those files are seldom altered, but copying say, my writing folder can lead to the backup media containing only older drafts of some documents. 3. It tells me nothing of files from an older copy that have been deletd/renamed since the last copy. jdupes can find old files on the destination media if the new file is just a rename, but it can't help with files that have been altered as well as renamed. I suppose what I'm looking for is a command line utility or script that executes the following pseudo code: Given directories source and destination: for every file found in both source and destination: if file.source != file.destination prompt user whether to overwrite one version of the file with the other or to add the files to a list for later examination. For every file only in source: search for match in destination. If match found prompt user towhich to rename to match. If not match found, copy to destination. For every file only in destination: search for match in source. If match is found, prompt user to which file should be renamed. If no match is found, prompt user whether to copy of delete. If anyone knows of command line utilities to help with this task, it would be greatly appreciated. _______________________________________________ Blinux-list mailing list Blinux-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/blinux-list
