5.0 out of 5 stars

Merely half an inch thick, and employing the same cover design - or lack of it - as the C Programming Language, this is probably the least pretentious looking book on my bookshelf. However, the look is misleading - there are very few books, regardless of length, that aim to teach you as much as this one, and even fewer than succeed in it.Unix programming environment might sound a rather ambitious title nowadays, when a tutorial on each specialized tool can easily exceed 400 pages. However, this one actually delivers everything that it promises. Kernighan and Pike start with the basic description of Unix file system and the basic set of commands, continue with the command shell, redirection and piping. Next come the filters: regular expressions, grep, sort, sed and awk. At that point, the reader is ready for the full-fledged treatment of the command shell programming. Next come standard I/O and Unix system calls, followed by the program development tools: make, lex and yacc. The course is concluded with a chapter on document formatting with troff. The chapters on I/O and system calls imply familiarity with the C programming language. The already mentioned tutorial on C by Kernighan and Ritchie, written in much the same style and spirit, can serve as the introduction to it. Also, while the book keeps up with its age remarkably well, there are some points where the described Unix system differs from the modern POSIX systems (most user commands are however backward compatible and still accept the old syntax). The required changes are really minor, but can nevertheles annoy an innocent reader. The book belongs to nowadays rare breed of books on computers written for engineers and CS students rather than for dummies and idiots. Although primarily written for individual study, it can be used for one-semester course on Unix (like in C Programming Language, the exercises are lacking solutions, though). I would love to see it made-up with POSIX syntax and generally reflecting the changes made to Unix during the past 15 years.
