Although exiftool is nothing specifically to do with scripting, I am writing a script that uses it to read and write some jpeg tags and have a question about exiftool’s operation that someone here might be able to help with.
Whenever exiftool writes one or more tags to a file, it creates a copy of the file with the new tags and leaves the original there just renamed …_original. Oddly, the Finder/Spotlight comments are moved to the new file (so the original no longer has them), but Finder Tags/Labels are not copied to the new file and this is a problem as I need to maintain all the original’s Labels.
Anyone suggest how to get exiftool to simply update the EXIF data of the file without having to create a copy first?
