CLI Reference Overview

Every other section on this site teaches concepts — why Kubernetes exists, how Terraform's state model works, what git rebase actually does to the commit graph. This section is the opposite: no theory, just the real commands, in the order you'd actually run them, verified against each tool's own docs rather than half-remembered.

Use it as a lookup, not a read-through. If you want the "why," the concept pages are cross-linked from every page here.

What's covered

• Linux & Shell — process inspection, file/permission ops, text processing (grep/sed/awk/jq), network diagnostics
• Git — beyond add/commit/push: interactive rebase, bisect, reflog, worktree, cherry-pick, stash workflows
• Docker & Compose — build/run/exec/logs, Compose, image and layer management
• kubectl — real verbs, resources, and flags for a running cluster
• Terraform — init/plan/apply, state surgery, workspaces
• Cloud CLIs — AWS CLI, Azure CLI, and gcloud, side by side for the same common tasks
• Package Managers — pip, Poetry, uv, and npm
