I have a huge backup of images from students' coursework - something like 100,000 of them. Because of the way they were collected a lot of them have tags on them which are screwing up my filing system so I'd like a way to clean all of them out. Is there a way to do this? I've had 'exiftool' suggested to me, is there a way to combine this with a recursive command or something to clean it all out?
If it helps, I'm using Gnome 16.04 and the exiftool is installed - although I'm still a bit clueless about it.
