About the course
Our Grep, SED, and AWK training course covers these three fundamental Unix utilities which remain indispensable tools for anyone working with Linux, macOS, or other Unix-like systems, from developers and system administrators to DevOps engineers and data analysts.
This hands-on workshop will equip you with the skills to effectively search for patterns in files using grep, perform powerful text transformations and substitutions with sed, and process structured text data with awk. You'll learn how to leverage regular expressions to their full potential and understand how these tools form the backbone of many scripting and automation workflows.
While the landscape of data processing has evolved, grep, sed, and awk continue to offer lightweight, efficient, and rapid solutions for targeted text operations, log file analysis, configuration management, and initial data exploration.
This course will not only cover the core functionalities but also highlight their relevance in modern contexts, demonstrating how they can be integrated with other tools and scripting languages for enhanced productivity in today's technology-driven environment.
Instructor-led online and in-house face-to-face options are available - as part of a wider customised training programme, or as a standalone workshop, on-site at your offices or at one of many flexible meeting spaces in the UK and around the World.
-
- Effectively search for text patterns in files using grep and regular expressions.
- Perform powerful text transformations and substitutions using sed commands.
- Process and extract data from structured text files using awk patterns and actions.
- Understand the fundamental syntax and operation of grep, sed, and awk.
- Utilise these tools for common system administration and development tasks.
- Incorporate these utilities into basic shell scripts for automation.
-
This practical course is ideal for system administrators, DevOps engineers, software developers, data analysts, security professionals, and anyone who regularly works with command-line interfaces on Linux, macOS, or other Unix-based systems. It's also beneficial for those looking to enhance their scripting and automation skills and gain a deeper understanding of text processing utilities.
-
To make the most of this training, delegates should have attended our Linux Intro course and/or have a basic familiarity with the command line and a general understanding of file systems in a Unix-like environment. No prior knowledge of grep, sed, or awk is required, as the course will start with the fundamentals. However, a basic understanding of regular expressions would be advantageous but not essential, as it will be covered within the course.
-
This grep, sed and awk course is available for private / custom delivery for your team - as an in-house face-to-face workshop at your location of choice, or as online instructor-led training via MS Teams (or your own preferred platform).
