Linux & Command Line

Backend Foundations

Explanation

Servers run on Linux. Learn files, permissions, processes, and curl so you can debug APIs in production.

Code example

bash
curl -i -X POST http://localhost:4000/api/skills \
  -H "Content-Type: application/json" \
  -d '{"name":"PostgreSQL"}'
ls -la
tail -f logs/app.log

Helpful resources

Exercise

Use curl to call a local API, inspect headers, and follow a log file with tail -f.
