Mastering Text Processing with Grep, Sed and Awk

Practical One-Liners & Terminal Pipelines | Search, Transform, Extract & Report like a Pro
What you'll learn
✓ Use Grep to find what you're looking for
✓ Use Sed to transform and clean output
✓ Use Awk to turn messy data instead reports or prettier outputs
✓ See how this knowledge ties into real-world examples and other tools.
Requirements
● Some terminal knowledge is useful (cd, cat, cp, mv, etc)
Description
Unlock the real power of the Linux command line with the three most essential text-processing tools every developer, sysadmin, and DevOps engineer needs: grep, sed, and awk.
Quickly, you'll go from basic pattern matching to building small pipelines that parse logs, clean configuration files, extract data from CSVs, generate reports, and automate tedious CLI tasks. All without leaving the terminal.
Why this course is extremely useful for general Linux users
Whether you're a developer debugging application logs, a sysadmin troubleshooting servers, a DevOps engineer analysing CI/CD output, or just a power user who spends time in the shell, these three commands appear in almost every serious pipeline you'll ever write.
• grep finds what you're looking for instantly (and filters noise)
• sed transforms and cleans text on the fly (search & replace, delete lines, insert headers)
• awk turns messy output into structured data (field extraction, calculations, grouping, custom reports)
Mastering them increases your productivity because you stop reaching for editors or GUIs for tasks that should take seconds. You'll also discover how these skills transfer directly into Vim (via ex commands), showing you that these skills transfer outside of the tools themselves.
What you'll learn
• Grep, fast filtering with basic flags, glob patterns, extended regex
• Sed, substitutions, deleting/inserting lines, in-place editing, ranges, multi-command scripts
• Awk, field-based extraction, conditionals, math & averages, arrays for grouping & counting, custom functions, BEGIN/END blocks, multi-line "programming language" scripts
• Ex, quick history lesson showing why sed/awk knowledge makes you instantly better at Vim's : commands
All lectures use real-world examples on server logs and CSV data, demonstrated live in a split-window setup (working terminal + slides).
Course structure
• Introduction
• Grep: Basics + Globbing & Regex
• Sed: Basic substitutions → Deleting & inserting → Advanced ranges, in-place & pipelines
• Awk: Fundamentals → Conditionals, math & custom output → Awk as a programming language
• Ex: The line editor that powers Vim (why your new skills transfer)
• Final wrap-up
About the Teacher
All my terminal courses are produced in the same tmux + slides style you'll see here — short, practical, no-fluff lessons designed for busy Linux users who want to get better at the CLI today instead of tomorrow. I work in the terminal every day and love helping people move faster without ever leaving their shell.
If you already enjoyed my Vim or Tmux courses with me, this course is the natural next step to turn your terminal into a real data-processing workflow.
Enroll now and start writing smarter one-liners by the end of today.
Who this course is for
■ Sysadmins and DevOps looking through log files daily
■ Linux powerusers
■ Developers wanting to do more in the terminal
■ Students wanting to flex on classmates with terminal one-liners
