PL100-WS: Shell Power unleashed – but how?

Web Seminar: Programming Languages – Linux/Unix

Experienced Linux/Unix administrators receive a practical introduction to the philosophy and efficient use of the shell. The course covers best practices to avoid complex pipe chains through shell-internal functions and awk. It addresses performance optimizations, code improvements, and time savings based on practical examples with a focus on professional shell scripting.

Agenda:

Location and function of the shell in the operating system

Shell built-ins and keywords instead of OS commands

Special variable expressions instead of pipe chains

Shell arithmetic instead of expr

Efficient control of shell interpretation

Complex data structures using eval

Regular expressions and ANSI escapes in the shell

Elegant performance and flexibility: awk

Q & A session

Objectives:

When administering via the Linux/Unix programming language Shell and Unix commands, there are often multiple ways to achieve the desired result. However, there are often significant differences in runtime, code brevity, and result accuracy. In this web seminar, we will demonstrate the background and applications of such optimizations.

Ask our expert the questions you've always wanted to ask about Shell and Unix commands, and gain the confidence to significantly accelerate and simplify your system administration.

Target audience:

The web seminar Unleashing Shell Power – But How? is ideally suited for:

Linux/Unix administrators
Linux/Unix system operators
Linux/Unix programmers
Software developers
Linux/Unix developers
Linux/Unix DevOps
Data processors

Prerequisites:

Knowledge of shell and Unix commands is beneficial.

Description:

You're an experienced Linux/Unix administrator but haven't had the time to truly understand the philosophy and workings of the shell? You feel that you're not using the shell efficiently and reliably, and constantly have to rely on obscure code snippets from the internet?

You're not alone: even shell scripts from well-known software vendors often cause frustration. Learn how to do it better! For example, instead of using complicated and resource-intensive long pipe chains, leverage shell builtins and awk code!

In this Web Seminar, our project- and practice-experienced instructor Prof. Dr. Albrecht Scriba will show you the original purpose of the shell and will unleash the shell power with practical examples to achieve dramatic performance improvements, code optimizations, and time savings in your work.
