"Unix Utilities" 2 days Next Public Offering: TBD; Help Us Schedule!

Course Description

This lecture/lab course shows the student how to harness the power of the UNIX utility programs through interactive shell commands and shell or AWK scripts. The most important UNIX utilities, including egrep, sed, dd, sort, tee, comm, tput, tail, find, and xargs are explained and illustrated in realistic programming examples. Students also learn how to do pattern matching using Regular Expression notation, and to write programs using the AWK language, an extremely easy but powerful predecessor to Perl.

We also have Linux and combined UNIX and Linux versions of this course.

Who Should Attend

System administrators, network administrators, data administrators, programmers, managers, clerical users, and others who wish to make the most of UNIX. Anyone who needs to write new programs or maintain existing ones that automate routine tasks, validate data, generate reports, convert text files into other forms, or perform numerical analyses will benefit from attendance.

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 be familiar with:

the hierarchical file system of UNIX and the special characters for Filename Generation (*, ? [ ])

file redirection

pipelines

basic UNIX commands, including cd, ls, cp, mv, cat, more, grep, & mail.
Previous programming experience is very helpful, but logically-minded individuals without such a background may also benefit.

Author & Instructor

Dr. Tim Maher wrote a course on the Bourne shell for AT&T in the early 80s, and taught it for many years to AT&T's customers and employees. Since 1986, Tim has taught shell programming to literally thousands of students and has written many sophisticated applications in shell languages.

For example, in the mid 1980s he created a friendly, menu-oriented user interface to UNIX for undergraduate students at U.C. Berkeley (using more than 8,000 lines of shell code). Later, he developed the first source code beautifiers for the Korn shell, C++, and Perl languages.

In the early 1990s, Tim wrote a Shell script of over 1,000 lines to control machine tools used by Seattle aerospace suppliers in the fabrication of Boeing aircraft parts.

In the late 1990s, he wrote software to manage the terabytes of data uploaded by customers who were using the Netscape Online Backup product.

As a recognized expert on Shell programming and the founder and head of Consultix, Dr. Tim Maher regularly teaches courses on a wide variety of UNIX, Linux, and Perl 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.

A former student says:

Read more testimonials and reviews of our courses and instructors. • Excellent teacher [Colin Meyer]—obviously knows subject as opposed to having just read manual previous night. Very helpful dealing with all questions, reglardless of depth.
