Grep exif data

view full story

http://www.unix.com – I would like to search for regex in the exif data of a large collection of files (mostly jpg, some nef). For instance "grep_exif Tokyo *.jpg" should return the file names of all files which have "Tokyo" in their exif data. Exiftool could be used to extract the data. I don't really need to grep all of the exif data, but only things like city, location, country, keywords, etc, So if there is a quicker or more convenient tool than exiftool that could be used instead. Two nice-to-have-not necessary requirements: 1. be insensitive to capitalization (Tokyo/tokyo/tOkYo/...) (HowTos)
