The output you get with the above command looks like this:
drutil(1) - interact with CD/DVD burners escputil(1) - maintain Epson Stylus inkjet printers hdiutil(1) - manipulate disk images mdutil(1) - manage the metadata stores used by Spotlight niutil(1) - NetInfo utility plutil(1) - property list utility smbutil(1) - interface to the SMB requester textutil(1) - text utility textutil(n) - Procedures to manipulate texts and strings tiffutil(1), - tiffutil(1) - manipulates tiff filesNow all you need to do is get the man pages for each of them (the manual for hdutil is very long!) for more info on how they each work.
[robg adds: We've run separate hints on most of the programs in the above list. However, I thought it was worth sharing the full list in this simple hint, as you may have missed some of these. I hadn't heard about escputil, for instance...]
