Subject: Sub-String

What's a good way to grab a sub-string from a string?  With string
implementation, I'm used to a substr() or mid() function where you can
specify where you want the sub-string to start and the return is everything
from that point on.

Here's an example:

    "/home/fred/file.ext".substr(11) => "file.ext"

What's a good equivalent way to do that in Ruby?
