get a list of files with the same tag (for example DateTimeOriginal)

[chc]

Is it possible to get a list of files with the same tag, like "DateTimeOriginal", in multiple directory? Or a list grouped by similar tags?
Thanks

Try the -if option.  Using DateTimeOriginal as an example, your command would be

exiftool -if "$DateTimeOriginal" -DateTimeOriginal /path/to/files/

Example, with only two of three files having DateTimeOriginal set.

If you're using Mac/Linux/PowerShell, then change the double quotes into single quotes, as the dollar sign has special meaning when there are double quotes around it.
