Intermediate Linux | Shell, Bash, Text Manipulation, Multitasking & More (TTLX2104)

Overview

Intermediate Linux: Shell, Bash, Text Manipulation, Multitasking & More is a two-day course designed to provide you with hands-on experience using standard Linux commands and utilities used for day-to-day tasks including file manipulation, program execution and control, and effective use of the shell and desktop environments. Throughout the course you’ll explore key concepts to Linux core functionality, while learning the system’s most commonly used commands. You’ll also learn the Bourne shell, Bash shell and Korn shell programming techniques you’ll need to read and modify existing shell scripts, and create your own. Data manipulation utilities and shell syntax for synthesizing command pipelines are also emphasized throughout the course.

Audience Profile

This is an intermediate-level course for attendees with basic Linux experience. Attendees should have experience with common UNIX/Linux user-level commands, such as moving, copying and editing files. Experience with the vi editor is a plus.
