Tag files from one directory if they occur in another

[frereroy]

I have a directory that contains a list of 30 files that have been published on the web in low resolution. I have another directory of the full size images + many other "second choice" candidates.

I would like to add the XMP-xmp "Rating: 5" to all the files in the full size image directory only if they occur in the low resolution directory.

Am sure that Exiftool could sort this out but do not really know where to start.

TIA for any help and enlightenment.

Are the filenames exactly the same or similar with a consistent naming pattern between the LR and HR images?

Is there a unique piece of metadata that matches between the LR and HR images?

You could do something like this if the file names are identical:

exiftool -if '-e "LOWRESDIR/$filename"' -xmp-xmp:rating=5 DIR

The above quoting is for Mac/Linux.  For Windows:

exiftool -if "-e qq(LOWRESDIR/$filename)" -xmp-xmp:rating=5 DIR

Works great - many thanks.
Am wondering if there is any action that Exifttol CANNOT perform

I'm still having trouble getting it to wash the dishes for me.
