How to reference a value in an -if statement

[imaginator]

Code Select Expand

-d
%Y

-if

...do something


I've tried different combinations of escaping #DateTimeOriginal but usually get back a message about

Code Select Expand

This takes a bit of Perl knowledge.  The Concatenation Operator needs to be used.  Your args file would be

Code Select Expand

-d
%Y
-if
(not $xmp:Rights eq 'Copyright © '.${DateTimeOriginal}.' Name, all rights reserved.')

Thanks. And much appreciated the comment about "...takes a bit of Perl knowledge". That makes me feel not so bad.
