linux Vim basic operating method

Recently, I have been relearning Unix with Ubuntu11.04, which I did not learn well before, but X Window of Ubuntu11.04 did not perform well under VMware7.1.4. It doesn't matter, just lay the groundwork for the command line.
Vi of Ubuntu is also not good to use, I made an Vim for learning, simply record its basic operation, spare, to provide you with a book "UNIX practical tutorial (5th edition)"
