LEARN BY DOING

Learn the Linux command in the mission

Understand the goal first, then act. Each level focuses on a core skill to complete observation, operation, verification or delivery.

From daily operations to system management

145 tasks, 237 manual entries. The courses are organized into three levels: common, advanced, and master, covering directory navigation, file organization, text processing, permissions, archiving, systems, networks, and services.

Read it at any time and practice as you go

Each command provides purpose, syntax, parameters, examples and complete documentation links; commands with corresponding levels can be directly entered into exercises.

• pwdShow current location
• lsList files and directories
• cdSwitch working directory
• cpCopy a file or directory
• grepFilter text by pattern
• dfView file system space

After learning, practice again

First go through the four-stage, 24-level introductory route, from sense of direction, document delivery to text screening, and then interspersed with different topics. Today's review is arranged according to the completion interval across days, mixing due topics and changing files and paths; after completing all ordinary levels of topics of the same level, the independent Boss actual combat will be unlocked. Combine commands in the same workspace to complete delivery, retention, troubleshooting, and recovery goals; Advanced and Master gradually add constraints. Depending on whether the final goal is achieved or not; update the mastery record after reviewing across days. Each topic also provides optional real-world terminal exercises.

practice environment

All exercises are completed in the simulation environment in the browser, the progress is saved locally, and export backup is supported. A subset of exercises for teaching terminal implementation commands; the manual notes differences in support range and true Linux.
