MWG and batch processing

[Mart]

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:

Code Select Expand

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:

To 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.
