Display warnings when editing image's metadata with JSON file

[Arckorus]

Hi,

I'm currently using Exiftool for a student project and I'm having a problem with warnings when editing image's metadata with JSON file.
Indeed when I modify metadata in this way, warnings are correctly displayed :

Code Select Expand

$> exiftool -File:ExifByteOrder="unauthorized value" 1.jpg
Warning: Can't convert File:ExifByteOrder (not in PrintConv)
Nothing to do.

But when I do this same operation with a JSON file, the console doesn't display warnings :

Code Select Expand

$> exiftool -j=1.json 1.jpg
0 image files updated
1 image files unchanged

1.json content :

Code Select Expand

[{"SourceFile":"1.jpg","File:ExifByteOrder":"unauthorized value"}]

Is it possible to display them with the command above?
I consulted the documentation, but without success.

Hi Pierre,

Add the -v option to see all of these warnings.

Hi,

Thank you very much, it works!
I missed that while reading the documentation.
