在一组备份中选择唯一的 .mp3 文件。 Mac, Unix

Question

I am currently reorganizing all my backups. I have the problem that in those various backups there are both different and same .mp3 files.

I was wondering if there is a program or code for mac which can search for all the .mp3 files in a map and it's underlying maps/directory's. And if possible the program also copy unique versions of those .mp3 files to another directory.

With kind regards, Bigsortvids

Answer 1

After a lot of time searching on google and other forums and by trying I have found the following command as an answer:

find /fromWhichDirectory "*.mp3" -type f -print0 | xargs -0 -I '{}' mv "{}" /toWhichDirectory

!!!! PAY ATTENTION that when you don't end the command with ctrl+c and you delete the files that where moved or copied to the toWhichDirectory terminal will try to replace the files with the files from fromWhichDirectory which in the case of moving(mv) you get irritating errors and in the case of copying(cp) all the files will be copied again.

I just wanted to delete some(3000) .mp3 files that didn't fit in the row and they just appeared again. Very irritating and long process, took me an hour to delete all the right mp3 files and empty the trashcan. I had to remove almost 100gb of mp3 );

Hope I helped someone with this answer, greetings, Bigsortvids
