I've never used Fedora or Red Hat. (No, wait, that's a lie. I have a 
disk somewhere for Red Hat 2.1, circa 1996 or so. I don't think Yum 
existed yet.)

Debian uses .deb packages, which can be installed using dpkg, dselect, 
apt-get or aptitude. The exam requires you to know ALL FOUR. (!) Even 
though in reality you'll only use one of these tools. (Usually aptitude, 
because dselect is utterly incomprehensible!)

Most distros derived from Debian use the same packaging system. Most 
other distros use RPM. But Gentoo uses the Emerge system, because it 
builds absolutely everything from source. It's a great way to expend 
compute cycles and disk space...

I never use RPM itself. I always use Zypper, but that's specific to 
OpenSUSE and isn't on the exam. Whereas Zypper can uninstall a package 
using the "remove" command, the exam requires you to know that this is 
the "-e" switch to RPM. Not u for uninstall or r for remove, but e - for 
no defined reason whatsoever.

But hey, that's Unix all over. Don't expect there to be any reason or 
rhyme to it, just memorise this crap.

PS. It especially amuses me how many commands let you specify the number 
of bytes of operate on with a -c switch. Because, as you know, 1 
character = 1 byte. Oh, wait...
