Hello!
I made ARGFILE (arg.txt) which contains:
-MWG:ModifyDate<FileModifyDate
-MWG:Description=test
testimage.tif
-execute
when I execute exiftool -@ arg.txt it will produce warrning output:
Warning: Tag 'MWG:Description' does not exist
Warning: Tag 'mwg:ModifyDate' does not exist - testimage.tif
Warning: No writable tags found - testimage.tif
0 image files updated
1 image files unchanged
I would expect it to work like exiftool "-MWG:ModifyDate<FileModifyDate" -MWG:Description=test testimage.tif
Is there something wrong with MWG tag because EXIF tag (e.g. -EXIF:ModifyDate<FileModifyDate) works just fine..
I'll see what I can do about this, but the work-around is to add
-use MWG to your command line.
This cool feature:
QuoteTo save typing, "-use MWG" is assumed if
the "MWG" group is specified for any tag on the command line.
doesn't seem to work properly with the
-execute option. I'll try to fix this in the next update.
Thanks for pointing this out.

Ah.. I remember reading about -use MWG but forgot it :)
This problem should be fixed in version 8.39, which has just been released.
