Catfish is a handy file searching tool for linux and unix. Basically it is a frontend for different search engines (daemons) which provides a unified interface. The interface is intentionally lightweight and simple, using only GTK+2. You can configure it to your needs by using several command line options. Supported backends are find, (s)locate, doodle, tracker, beagle, strigi and pinot.
