Remove all keywords

[Lysvik]

I tried some hours with exiftool to get this job done but I could not get it to work. Files are originally managed with Adobe Brigde where each PEF (raw imagefile) has his own xmp file.

Target is to clean all keywords from the PEF files before importing the PEF files into Aperture.

Some of the commands I tried so far:

Code Select Expand

exiftool -overwrite_original -IPTC:Keywords=Kroatie *.PEF

This one add Kroatie but the old keywords are still there

Code Select Expand

exiftool -overwrite_original -keywords=Kroatie *.PEF

The same result as before, the old keywords are still there.

Can someone advise witch code I should use?

Try using -mwg:keywords=Kroatie to see if this helps.

See the MWG tag name documentation for more information.

Thansk Phil, this code works, it wiped out most (strangely not all) keywords.

This is the code I used:

Code Select Expand

exiftool -r -overwrite_original_in_place -mwg:keywords= *.PEF *.jpeg *.jpg *.psd

Unfortunately it runs with a limitation, because the parameter -r is not running the command in the subdirectories. Running the command apart on each a folder works, so it does the job. If you have a solution for this -r issue, please advise.

I'm not sure, but when -r is used, then path to files should be specified. Try something like:
exiftool -r -overwrite_original -mwg:keywords= -ext pef -ext jpg -ext psd "c:\my Files\testing"

Bogdan gives good advice.   You must specify a directory name for the -r option to be meaningful.  If the files are in the current directory, then a simple "." will suffice.  And the -ext option controls what files are processed in the directory, otherwise by default all writable file types are processed.

Concerning the keywords that aren't deleted, I can tell you exactly what is going on if you send me a sample image (philharvey66 at gmail.com).
