in reply to meaning of if ($file !~ /\.tar(\.gz)?$/)

Matches all $file except .tar and .tar.gz endings. 

if ( $file !~    # scalar $file tested for not matching
          /\.tar     # an ending of .tar
                  (\.gz)?   # followed by an optional .gz
                       $    # at the end of the name
               /x)

    thank you, your answer is clear.

    it was the optional part that confused me :(

    best regards.
