RE: How to extract suffix from a filename?

[Glen Coakley <gcoakley at mqsoftware dot com>]

This breaks on extensions that are not three characters, such as ".html".
(Note: This includes the period.) The following will work for any length
extension.

    ext=`basename $filepath | sed -e 's/\(.*\\.).*/\1/g'`

If you don't want the period:

    ext=`basename $filepath | sed -e 's/\(.*\)\..*/\1/g'`
