Over the years, KornShell has evolved into a full-featured, powerful shell language. Familiarity with KornShell enables system and network professionals to extend the user environment and automate complex system-administration tasks for huge productivity gains. Bourne and C shell programmers will appreciate KornShell's superior string handling, stronger data typing, and broader capabilities. Hands-On KornShell93 Programming is a self-paced tutorial that introduces you to the essentials of KornShell programming. Based almost entirely on short, focused examples that demonstrate central concepts and effective programming techniques, it will quickly bring you up to speed. The book reflects the newest version of KornShell, KSH93. It also provides coverage of significant developments, such as CGI programming with KornShell, and offers an in-depth look at KornShell string handling. Humorously written, the book makes it easy to learn KornShell essentials, including data types, math, pattern matching, conditions, loops, menus, command-line arguments, functions, start-up scripts, I/O, strings, variables, background processes, and CGI scripts.Highlighted "Beware" sections will warn you of potential pitfalls and keep you on the track to learning effective KornShell programming.
