Mac OSX

I sold off my cube so I don't have an OSX computer to test / poke around
on.

I have a friend who is running out of space on his main hard drive and
it seems to me that we could either move his /Users (which is the users
data directory) to another hard drive or clone his hard drive to a
larger hard drive (preferred).

Does anyone know ???

is the dd command part of BSD? OS X on Macintosh?

is there something like /etc/fstab?

how about fdisk?
