Title: Too many errors. A nice effort but not proofed well enough.
Review: While this book is unique in its attempt to comprehensively cover all three shells, Awk, Sed, and Grep, the many errors don't leave one with confidence in what one reads. If one can get past the syntax errors, the book may be worthwhile. e.g. !#/bin/csh -f should read #!/bin/csh -f . Back quotes and single quotes should match in C programing but do not in the examples shown in this text.
