Find duplicates without case sensivity

[Fulco]

This command prints the keywords and subject of files with duplicate keywords or subject (for example Bird, Bird):

exiftool -if '${Keywords;NoDups(1)} or ${Subject;NoDups(1)}' -p '$keywords' -p '$subject'

It does however not print duplicate keywords/subject with a different letter case (for example Bird, bird).

Is it also possible to print duplicates without case sensivity?

Thanks for any suggestions.

Hi Fulco,

This should do it:

exiftool -if '${Keywords;$_=lc;NoDups(1)} or ${Subject;$_=lc;NoDups(1)}' -p '$keywords' -p '$subject'
