Is there a way to extract EXIF information of all images within a directory (into an output file)? Preferably I also need GPS data but this is not essential.

I only ask, as I have a number of directories with a large number of image files within, so automating the EXIF extraction would be useful.

    Do you need something more elaborate than for example for file in *.jpg; do echo "=== ${file} ===" >> outputfile; exiv2 "${file}" >> outputfile; done? Or find . -type f -name '*.jpg' -exec exiv2 '{}' ';' > outputfile (though that, as is, might not include the image file names; it should be easy to adapt, though)? – a CVn Dec 3 '13 at 10:27
  • I'll give this a go, will modify it to include file names. Thanks for the response! – davidbain Dec 3 '13 at 10:53

With exiftool:

exiftool -r . > exif.txt

(remove the -r if you didn't intend to recurse into sub-directories).

Note that GPS data usually is in EXIF tags.

You can use jhead to do this.

You can do a loop to parse each file, then grep the pattern you need.

Along the same lines as exiftool there's also exiv2. Works similarly from the command line.

$ exiv2 *.jpg > exifs.txt

It lacks a recursive switch so you'd need to use a find command to walk it through a directory tree of image files.
