I have a 1 TB hard drive which I have been using for backups for a few years. The problem is I only did backups by hand. So now I have a lot of duplicates saved up. Is there a software or a script that will scan the drive for duplicate files, let me choose what to keep and what to delete? Bonus points if it shows me the time and date of last modification to the file.
There is a good software with a GUI to do that called
Fslint that you can install by your default repositories:
apt-get update && apt-get install fslint
With this software, you can detect duplicates files by using the names but also the content (may be longer with content).
