Objectives:

When used correctly, shell and various Unix commands are often the most efficient interfaces for administering systems and applications. The course PL100 Shell, awk, sed: Basics introduces you to the fundamentals and programming with these tools.

Unix shells and commands can do much more than just execute simple commands interactively and then perhaps filter them roughly with grep. With precise knowledge of the interpretation steps of the shell and data processing using powerful tools such as awk, sed, grep, sort, tr, and others, you can quickly accomplish tasks that many graphical administration tools cannot offer. The course focuses on bash, but also points out differences to sh and ksh.

Advanced knowledge is offered in the training PL101 Shell, awk, sed: Advanced.

Target audience:

The course PL100 Shell, awk, sed: Basics is designed for participants who already have basic UNIX/Linux knowledge and now want to acquire in-depth knowledge of the system's central communication interface in order to simplify their work with their own programs and scripts.

The workshop is ideal for:

System Operators
System Administrators
Programmers

Prerequisites:

To be able to follow the learning pace and course content in the workshop PL100 Shell, awk, sed: Basics effectively, basic knowledge of the UNIX operating system is advantageous. We recommend attending the seminar LI100 Linux Basics in advance.
