I always use top(1)

Don't know the answer to this one (assuming you can't just cp(1) or
mv(1) them).

No, but both sh(1) and csh(1) are statically linked and in /bin on
FreeBSD systems and so are accessible even if you boot single-user
(only / mounted). If you *really* want bash(1) for root then
statically link it and put it in /bin.

Use the ports, http://www.freebsd.org/handbook/ports.html

Linux support is in the kernel by default but some (all?) Linux apps
require the linux_base port as well:

	# cd /usr/ports/emulators/linux_base
	# make
	# make install
