The explainer
Start typing. Each token in the command is wrapped in a colored pill: the command itself in gold, flags in blue, positional arguments in violet, operators in red. Below the command, you will see a card for each token explaining what it does. A line connects every token to its card so it is clear which piece of the command produced which explanation. Combined flags like -lah are split into their individual letters automatically, and numeric chmod modes like 755 are decoded bit by bit.
Test yourself
Active recall beats passive reading. The quiz draws from the same database the explainer uses — each question shows a real command with one piece blanked, or asks which command does a given thing. Score and streak track across the session. Skip if you don't know it; click an explanation to send the underlying command to the explainer above.
The complete command tables
Below is the full set of commands taught in Rolling Thunder Security, organized by category. Use the filter to narrow down to a command name, flag, or task; click Explain on any row to send that command to the explainer above. Every row here is also a valid input for the explainer.
