Where the commands you've learned become automation. You'll write real bash scripts - with variables, parameters, conditions, loops, functions and proper error handling - and the grader runs them to check they actually work.
This is the course that turns "someone who knows Linux commands" into "someone who automates Linux".
make build # build the image once
make start S=01-bash-basics # a clean ~/sandbox to write scripts in
# ...work in the container; when done, type 'exit' (or Ctrl+D) to leave, then:
make verify S=01-bash-basics # runs your scripts and grades them
make reset S=01-bash-basics # fresh startNeeds Docker and make (both provided in GitHub Codespaces).
| # | Section | Course § | Skills |
|---|---|---|---|
| 01 | Bash Basics | 1 | shebang, chmod +x, variables, $1, $(( )) |
| 02 | Conditions & Loops | 3 | if/elif/else, for, while |
| 03 | Functions | 4 | defining/calling functions, params, local |
| 04 | Error Handling | 5 | exit codes, $?, set -euo pipefail |
| 05 | Files & Automation | 6-8 | read/write files, checksums, sleep, a provisioning script |
Each section: README.md (3-tier tasks) · seed.sh · verify.sh (runs your
scripts) · solutions.md.
Unlike a quiz, the grader executes your scripts with known inputs and checks the
output and exit codes - e.g. add.sh 20 22 must print 42, deploy.sh with no
argument must fail. So your scripts have to genuinely work, not just look right.
Stuck on the how? Each section's solutions.md has the full script.
