+15 XP per step · +75 XP for completing the quest
In the Federation Combat Systems Lab, each tool is connected to the next via pipes. The output of one command becomes the input of another — like an assembly line where each station does one job. Master the pipe and your command power multiplies.
Primary Objective
Use pipes with grep, sort, and uniq to filter and transform data.
