  • this takes every jpg in the current directory and changes the exif data for manufactur and model. in my case i change it to LOMO LC-A because my scanner puts his data in there :]

    for f in *.jpg; do exif --ifd=0 --tag=0x0110 --set-value="LOMO LC-A" --output=$f $f; exif --ifd=0 --tag=0x010f --set-value="LOMO" --output=$f $f; done }

  • The command renames all files in a certain directory. Renaming them to their date of creation using EXIF. If you're working with JPG that contains EXIF data (ie. from digital camera), then you can use following to get the creation date instead of stat. * Since not every file has exif data, we want to check that dst is valid before doing the rest of commands. * The output from exif has a space, which is a PITA for filenames. Use sed to replace with '-'. * Note that I use 'echo' before the mv to test out my scripts. When you're confident that it's doing the right thing, then you can remove the 'echo'... you don't want to end up like the guy that got all the files blown away.

What Others Think

Use convert (also from ImageMagick, same arguments) instead - creates new file instead of overwriting the existing one.
