I was never able to find a decent piece of code that was able to parse out the extension of a given file delimited by a '.' regardless of how many '.'s were in the filename

While I do admire your industrial spirit, you can already do this with File::Basename ...

use File::Basename;

my $fname = "/usr/local/isp/system.update.perl";
my ($name, $path, $suffix) = fileparse($fname, '\.[^\.]*');

print STDOUT $name, "\n";

The key to this working is the regular expression passed to the fileparse method - The regular expression in the example above matches the suffix of a file as being the last dot and what follows it, excluding any subsequent dots ([^\.]).

 

perl -e 's&&rob@cowsnet.com.au&&&split/[@.]/&&s&.com.&_&&&print'
