Out of the thousands of JPEG files in my collection, some do not have any EXIF information. For these files, I would like to fill up the DateTimeOriginal EXIF field with FileModifyDate info from the OS. This lets me rename all files based on their DateTimeOriginal.
Can someone help with a command that lets me selectively run the command:
exiftool "-DateTimeOriginal<FileModifyDate" <filename>
on those files that do not have DateTimeOriginal populated already? Thanks!
Try this :
exiftool -if "not defined $DateTimeOriginal" "-DateTimeOriginal<FileModifyDate" <filename>
Test if first, of course, but it should work.
Your solution is so much better than mine. I wrote this highly inefficient script:
for file in `find -name *.jpeg`
do
exiftool -time:all -s $file | grep DateTimeOriginal >/dev/null
if [ $? != 0 ]
then
echo $file
exiftool "-DateTimeOriginal<FileModifyDate" $file
fi
done
I'll try yours and let you know if it works...
Also, you don't need to use "find" and loop over files. See common mistake number 3 (https://exiftool.org/mistakes.html#M3).

exiftool -if "not defined $DateTimeOriginal" "-DateTimeOriginal<FileModifyDate" <filename>
totally worked for me. And I learned some new things. Thanks.
