Linux Practice
Learn how to work a real Linux system from the terminal - navigate and inspect the filesystem, manage files, permissions, and processes, script the shell, and administer users, services, storage, networking, and security the way it is done in production.
Linux CLIFile & Directory Operations
Learn how to create, copy, move, and link files safely - idempotent scaffolding, copies that preserve permissions and timestamps, guards against clobbering newer work, and hard and symbolic links in place of wasteful copies.
Project Scaffolding
Create a nested project skeleton in one idempotent pass - rerun-safe, existing content untouched.
Safe Reorganization
Copy and move files preserving permissions and timestamps, with a guard that never clobbers newer work.
Links Not Copies
Replace wasteful copies with hard links, track a replaceable target with a symlink, and hunt down broken links.
Release Directory Builder
One deploy tool: scaffold the release, copy preserving, hard-link unchanged assets, atomically swap current.
About this path
This path starts with the Linux terminal itself: moving around the filesystem, and working with files and directories. You don't need any earlier experience with Linux or the command line. The file operations module covers creating, moving and linking files safely, and ends with a release directory builder.
