The good news is that you can eventually find out how commands work and then use them effectively. The book does a fair job in this area.

The bad news is that often times you need to mix and match commands.

The book could be fixed in the following manner.

* List all commands alphabeticaly.

* List the grouped-subsections as indexes in the back.

* Expand on a "see-also" ability in the book.
