Title: A fair book; not great, not bad.
Review: I purchased this book thinking it would help me learn Linux Shell Programming. It did not. First, the material is too high level. Second, some of us are still constrained to the original Bourne shell. The book does not cover the Bourne shell. For example, why does the following script not work:if [$# -lt "1" ]thenVAR=$1fiAnswer: There is no space after the opening square bracket. I found that out from an online tutorial that I can read for free any time I want.Why didn't I send the book back, or sell it? Answer: I would have to pay for shipping, or receive less than I paid. At least it looks pretty on my bookshelf.
