Hi Monks
I have this regular expression:
if($filename=~/(\w+)\.(\w{3})/gi){print "\nThis is a match::$filename\
+n"}else{print "\nNOMatch::$filename\n";}

[download]

I need to make sure that the file name has letters or _(underline), but no spaces and followed by a .(dot) and finally the three letters extension, but I can't figure it out the right match to prevent stranger characters entered for the file name, can anyone help on that?
Thanks a lot!
