使用Exiftool创建没有SourceFile的数组

Question

I would like to use Exiftool to create an array of -Artists for all files in a directory. Using the exiftool command below works but the output is not desirable:

C:\exiftool.exe -Artist Dir

The output looks something like this:

======== E:/File1.jpg
Artist                          : user1
======== E:/File2.jpg
Artist                          : user2
    1 directories scanned
    2 image files read

I would like the output to look something like this:

user1_user2

Or at least a simple array or output like:

user1
user2

Answer 1

To expand upon the answer I posted in the exiftool forums :
exiftool -q -s3 -Artist DIR

This will output each Artist tag on a line by itself, like your second example.

-q - Suppresses normal informational messages. This will suppress the file name listings.
-s3 - Short output format. In this case, the addition of 3 to the option only prints the values of the tag.
