Interactive Bash Scripting

This free interactive bash scripting course takes you from writing your first shell script to building practical automation tools, all through hands-on exercises you run directly in your browser. Starting with script fundamentals like the shebang line, file permissions, and execution modes, you move through variables, quoting rules, special variables, and command-line argument handling before tackling conditionals, loops, and reusable functions. Every concept is practiced immediately, so the syntax sticks through doing rather than reading.

The course covers the full range of intermediate bash topics: string operations and pattern matching, arrays including associative arrays, and file processing techniques for reading, writing, and parsing data files. You will also learn error handling strategies, exit codes, and debugging approaches that make scripts reliable in real environments. The final module puts everything together with backup scripts, log analysis scripts, and automation challenges that mirror tasks you would actually face on a server or in a workflow.

This course suits developers, sysadmins, data analysts, or students who already know the Linux command line and want to write scripts that save time at work or in their studies. No special software is needed. Finishing the course and passing the final exam earns you a certificate of completion you can add to your LinkedIn profile or resume.
