Yes I am trying to collect the file (the result will only produce 1 match) And I need that into a variable that can be used for the processing.

You already have the test in the loop and could just write a subroutine and pass it $file and do all your work there. If you want to hold on to those fiels which match your criteria, then use another array to capture as in @matchedfiles = grep( /*.test.*/, @files ); Either way, you have the data in place or the other.
