Just a quick link to a completely free and legal pdf.
It is called "Ubuntu Pocket Guide and Reference" available in print ( you pay for this) or as PDF for FREE.
Great little book - lots of Ubuntu info for 8.04 & 8.10 - so it is current.

I have one and often refer to it even though I am on Kubuntu 8.04 64 bit.
As they say in the classics, teemac, Danke *grin*
