The published estimate is 6 to 8 hours. Your pace will depend on how much you repeat the practice.

Do I need to install anything?

No installation is required to start the guided free chapter. Later lessons explain the real tools, files, and operating boundaries relevant to the skill.

What technology is covered?

The syllabus and these stated outcomes are the source of truth: Read the prompt, locate yourself, and find trustworthy help; Navigate and inspect files without losing context; Create, copy, move, and remove files with preview and verification habits; Search text, route standard output and errors, and read exit status as evidence; Predict single quotes, double quotes, variables, globs, and PATH behavior before pressing Enter; Manage permissions, executables, links, archives, and checksums safely; Diagnose a terminal mistake and produce a clear handoff packet.
