Practice exercises for the Vim course. Vim is the editor that's on every Linux server - when you SSH into a box to fix a config, Vim is what's there. These exercises build real editing fluency, auto-graded inside a disposable container.
- 🐧 Real Vim, real files - edit in an actual terminal Vim, like on a server
- ✅ Auto-graded - the grader checks the file you produced
- 🔁 Resettable -
make resetrestores the starting files - 🎯 DevOps-flavoured - every task is the kind of config edit you'll do for real
make build # build the Vim image once
make start S=01-insert-and-save # shell with files seeded; edit with vim
# ...work in the container; when done, type 'exit' (or Ctrl+D) to leave, then:
make verify S=01-insert-and-save # grade your edits
make reset S=01-insert-and-save # fresh startYou need Docker and make (both already provided in GitHub Codespaces).
| # | Section | Skills |
|---|---|---|
| 01 | Insert & Save | modes, i/o, :wq, :q! |
| 02 | Navigate & Edit | hjkl, gg/G, dd, yy/p, u |
| 03 | Search, Replace & .vimrc | /, :%s/old/new/g, ~/.vimrc |
Each section: README.md (tasks) · seed.sh (starting files) · verify.sh
(auto-grader) · solutions.md.
Vim is interactive, so there's no way to grade keystrokes - instead each task asks
you to transform a file, and the grader checks the result. You genuinely have to
make the edits in Vim and save them. (Stuck on the keys? Each section's
solutions.md lists the exact sequence.)
