Exif grep
 
Is there a grep command for exif data in image files, particular for the exif location?

I could use imagemagick's identify command and pipe it through grep, but that would take forever if I ran it on thousands of files. So ideally I'd like something that runs reasonably fast.

Any suggestions?

There is no grep specifically for exif data---you just have to have the right stuff in the regex search field.

With any tool like grep (tools that work on printable character sets), I don't know what happens when they hit binary data.

finally, why would you assume that any tool would be faster than ImageMagick--some may be, but surely others are slower.

Perl maybe ?. exiftool.

I only tried "identify" which extracts all kind of information but takes about a second on my computer for a single file which is certainly too much if I want to use it on many files. Perhaps there is some way to extract only part of the exif data (I am only interested in a small part of it anyway) and do it quicker.

exiftool seems to be quicker. Perhaps exifprobe could be helpful as well.

Did you have a look at exiv2?

I'm not sure about other distro's, but it is part of Debian.

debian is perfectly fine. Will have a look. Thanks.
