creating unique identifier tags

[neebah]

I am trying to add a unique iterated identifier to a folder of files using the XMP-dc identifier tag using the following command

"-identifier=Digital:05:2005:'${FileSequence;$_=sprintf('%.5d',$_+1)}'" DIR

but all I'm getting as output is Digital:05:2005:${FileSequence;$_=sprintf('%.5d',$_+1)}  Digital:05:2005:"photos id number in folder"

This is common mistake 5c.

Also, you have some extra quotes there.
