replace an empty string for exiv2 output

Question

I'm trying to collect image metadata using exiv2 tool.

I do exiv2 -q -K Xmp.photoshop.Credit image.jpg if image haven't any value for such field, I don't get anything in the console. How I can replace an empty output by some stub like 'empty' word?

I guess you can replace it with code below:

exiv2 -q -K Xmp.photoshop.Credit -g Xmp.photoshop.Credit=empty image.jpg

Couldn't find the file where you run exiv2, are you sure you wrote the path of the file correctly? – mrbravo Mar 14 '23 at 19:35
yes, I've run this script in the same directory as I run working exiv2 -q -K Xmp.photoshop.Credit image.jpg with empty output. – K. S. Mar 14 '23 at 19:39
I edited my answer again, I hope it helps – mrbravo Mar 14 '23 at 19:45
It doesn't throw an error now, but unfortunately it prints the same empty output as my script – K. S. Mar 14 '23 at 19:54
I'm thinking but i don't know why you are seeing this result. – mrbravo Mar 14 '23 at 21:28
