(I read a load of these cos I didnt understand it much, but now thanks to these
tutorials and help from Brian and John I have a good understanding of what the
hell I'm doing with it!)
Here are the basic commands
Can be confusing, read a few other tutorials before coming near this one
This one is quite good, it explains what's happening when you type commands
This one's *ok* but goes off the topic, for what we'll be needing, near the end
I haven't read it, I'm tired ok! But it looks *very* comprehensive and good! I must get around to reading it..
