The Amiga is blessed with a multitude of "directory utilities", perhaps more than any other platform. Also, the quality and usefulness of Amigas dirutils were better, IMHO. Some were ported to other platforms. Checkout Worker on Linux.
These are some of the best available for Amiga on Aminet:
Directory Opus - probably the most configurable. You can dl other ppls config files and see how they are using it.
Ordering - lightning fast even at 7 Mhz, one of my favs.
DiskMaster - enjoys a large following
ClickDos - older, very small, fits on a boot floppy
Sid - older but good, eclipsed by the top 3 above
