Linux and UNIX Tools and Utilities Training

Course Outline

To realize the full processing power of your UNIX/Linux system, you need to choose the right tools and use them in the right combination. In this training course, you learn how to leverage the many tools and utilities in the UNIX operating system to upgrade your UNIX/Linux administration skills, maximize productivity, and streamline tasks by adding shell commands, filters, and languages — like awk.

Linux and UNIX Tools and Utilities Training Benefits

  • In this Linux and UNIX training, you will learn how to:

    • Build and use UNIX/Linux tools and utilities.
    • Perform complex search strings using regular expressions.
    • Explore extended regular expressions with grep, sed, and awk.
    • Employ text filters to manipulate text and data.

  • Prerequisites

    You should have familiarity with user-level UNIX commands, such as ls, rm, cd, cp, mv, and mkdir, and have knowledge at the level of:

    • Learning Tree course 428, {course:428}, or
    • Learning Tree course 143, Introduction to Linux Training.
