CLIP
Shared foundation
Command-line fluency, Linux fundamentals, reconnaissance, scripting, credentials, and evidence
ctf / practice and transfer
Learn Linux through a browser-based CTF
Start in a terminal with no setup. Build command-line fluency through open, structured scenarios, then carry those habits into live targets that do not know what you are expecting.
01 / the route
Follow the work from explanation to transfer
CTF at CLI-Games is not one difficulty ladder or one kind of player. Start with documentation when you need context, train in the open when you want repetition, then take that knowledge to The Range when you are ready to work independently.
Documentation
Understand the terrain
Start with practical documentation for capture the flag, Linux fluency, and the habits that make a terminal useful. The Wiki is there when you need the map, not a gate you have to pass before playing.
Read the documentation →Training
Build the habit
Work through an open skill map from command-line fundamentals into reconnaissance, scripting, exploitation, forensics, and analysis. Guidance is available when a technique is new; every scenario remains open.
Explore CTF training →The Range
Test the transfer
Take those habits into rotating live challenges on isolated Linux infrastructure. Investigate an unfamiliar target, recover objectives, and see what survives contact with a real system.
Enter the live challenge →New to the terminal? Start with the foundation route. Already comfortable in Linux? Choose a harder scenario, roam the map, or enter The Range and see what you actually remember.
02 / why the terminal
The useful layer sits beneath the interface
The goal is not to memorize commands for their own sake. It is to know how to inspect a system, follow evidence, test an assumption, and keep moving when the abstraction stops helping.
CLIO
Offensive practice
Scoped exploitation, privilege escalation, lateral movement, reporting, and accurate remediation
CLIA
Defensive analysis
Network forensics, artifact recovery, incident reconstruction, and reproducible handoff
