in reply to elements not reversing inside a map

You are doing a 'reverse "filename.ext"' which reverses the string into "txe.emanelif". You want to perhaps do this: 
> perl -le '$,=":";print reverse split /\./, "filename.ext", 2'
ext:filename

 Edit: I realize that you are actually wanting to split on the last 'dot' to get the extension; that's why you did the string reverse. Here's a better way: 
perl -le '$,=":";print reverse( "filename.ext" =~ /(.*)\.([^.]+)$/ )'

    Unfortunately, that will not do what I want when the filename contains a '.' 
    perl -le '$,=":";print reverse split /\./, "filename.200505.ext", 2'

>200505.ext:filename

    when I would want (unbeknownst to all) ext:filename.200505

      To parse the file extension, just capture the text following the last .:

      $filename =~ /(?<=\.)([^.]+)$/;
