CMD Challenge
Test your command-line skills with real shell challenges

CMD Challenge is an interactive platform where users solve progressively difficult Unix/Linux command-line tasks directly in a browser-based terminal. Each challenge requires crafting a one-liner shell command that produces the correct output. It tests and builds practical command-line proficiency through hands-on exercises.
Users are presented with shell challenges in a browser-based terminal and must type a single-line command that produces the expected output to advance.
