Hello wise monks! I have users uploading files on my server, and occasionally they use a filename that the server doesn't like (such as chapter#2.doc). I want to get rid of all non-word characters in the files they upload, but I want to keep the \. for the extension. Right now I have this: 
# get the file from the form and call it $file
$file =~ s/(.*)\.(.*)$/$1/;
$ext = $2;
$file =~ s/\W//g;
$file = "$fileName\.$ext";

This works fine, but I don't like it. Is there a way to say "match all non-word characters except \."?
