Best-selling author Ellie Quigley is back!The fourth edition of Unix Shells by Example has some new features but it'sgoal remains the same: Take the entry-level programmer though thefundamentals of programming the bourne, bash, korn, and C shells.In this thorough revision, readers will enjoy updates that fall into three newchapters:1) The innovative "Shell Programming Quick-Start" chapter designed to getexperienced programmers (but not shell programmers) writing working anduseful code after only 15 pages.2) A chapter on debugging shell scripts. Previous editions of the book lacked adebugging chapter, and in teaching her classes Quigley realized the importanceof teaching proper debugging techniques at the very beginning, whenprogrammers are learning the language.3) Shell Programming for System Administrator's chapter: walks the readersthrough important shell scripts found on Unix and Linux systems.In addition, Quigley's coverage of the key Unix utilities: awk, sed, and grep hasbeen updated to cover the GNU/Linux versions of these, also important forreaders working on Linux systems.Finally, the chapter covering the Linux bash shell has been greatly enhancedand updated to the latest version of bash (2.05). Again, this is really importantfor Linux users.
