Course Description
This course teaches the use of shell features needed in advanced programs, such as interactive menus, idiot-proof interaction, option processing, high security, precise numeric calculations, client/server design, interpretation of custom command languages, program debugging aids, and efficiency optimization. The techniques that are covered work with the Bourne shell, the System V shell, the Korn shell, and POSIX shells (such as Linux's Bash).Benefits
Mastering the shell unleashes the power of hundreds of UNIX/Linux utilities to the user or programmer! Knowing how to exploit the advanced features of these shells allows the programmer to solve difficult problems quickly while avoiding the overhead of a compiled language.Who Should Attend
System administrators, programmers, and users who want to make the most of UNIX/Linux.Prerequisites
Students should be experienced with one of the following text editors: vi, emacs, or pico (or another locally available editor, for on-site classes). Students should also have familiarity with the hierarchical file system and basic commands such as cd, ls, ln, chmod, grep, ps, & kill, and have at least six months of active experience in Bourne, Korn, or POSIX shell programming.Author & Instructors
Dr. Tim Maher wrote a course on the Bourne shell for AT&T in the early 80s, and taught it for many years. He has written many sophisticated applications in shell languages, including an eight-thousand line user interface used by students at U.C. Berkeley, and a source code beautifier for the C++ language (published in Dr. Dobb's Journal). Tim is a recognized expert on Shell Programming, and as founder and head of CONSULTIX, he regularly teaches courses on a wide variety of UNIX/Linux topics.CONSULTIX instructors are renowned for their ability to communicate complex concepts in simple terms and to make the study of dry technical material enjoyable.
