I had a need to rename files that have periods in the filename to use an underscore instead of a period but leave the period separating the file extension alone. I have a perfectly good solution that does exactly what I need it to do. However, I'm wondering if there isn't another, simpler solution instead of the three lines that I could use instead (some sort of one-line solution). The question is more academic than anything since I have an answer, just looking to expand my knowledge some :-)

The code sample below is very very stripped down to just the core elements: 

use File::Basename;

 foreach (<DATA>) {
          chomp $_;
          ($file,$base,$ext)=fileparse($_,qr/.[^.]*/);
          $file =~ tr/\./\_/;
          print "Change: $_ to ${file}${ext}\n";
 }

__DATA__
test0.file0.new_20060411.zip
test1.file1.new_20060411.zip
test2.file2.new_20060411.zip
test3.file3.new_20060411.zip

Any insight's would be appreciated.
