Linux Workshop

Learn Linux commands through 40 hands-on challenges.

How to Play

source ./play

This starts the game. You'll be asked for a team name and player name, then dropped into the levels/ directory at Level 0.

Submit a password

submit <password>

The server knows your current level, so submit works from any directory. Type it from inside a level folder or from the root — it always sends the password for your current level.

Level 0

Your first password is:

foss_linux_hello123

Run submit foss_linux_hello123 to complete Level 0 and advance to Level 1. Then cd level_01 and solve the challenge.
