List of filenames with no keywords

[Joanna Carter]

Is it possible to get ExifTool to list all files that possess a tag (like

Code Select Expand

xmp-dc-subject) but that do not contain keywords?

[greybeard]

What about this?

Code Select Expand

exiftool -if '$XMP-dc:subject eq ""' -fileName -T .

Are you checking for specific keywords or for a tag that exists but contains no values?  @greybeard's command works for the latter.  The former can be a bit more complex.
