When you quote the string on the right hand side of =~ it changes to a simple string match instead of a regex match. It is sometimes difficult to specify a regex literally (and unquoted), so it's best to use a variable as shown in Steven's reply to you. The quoting is most likely unnecessary on the left hand side as well. -- Visit serverfault.com to get your system administration questions answered.
