## Overview

This repository is a Linux sysadmin reference, not an executable application: users consult the command catalog or a task-specific scenario, then adapt the examples for administration or troubleshooting. Its documented capabilities span package, file, system, network, security, service, cloud, and automation tasks. The README supports these relationships; no source excerpts were provided, so the graph does not infer internal calls or execution behavior.

Main entry points: [`commands.md`](https://github.com/shantoroy/linux-sysadmin-cheatsheet/blob/main/commands.md) (Command Catalog), [`scenarios/text-manipulation.md`](https://github.com/shantoroy/linux-sysadmin-cheatsheet/blob/main/scenarios/text-manipulation.md) (Text Manipulation), [`scenarios/file-management.md`](https://github.com/shantoroy/linux-sysadmin-cheatsheet/blob/main/scenarios/file-management.md) (File Management), [`scenarios/filesystem-management.md`](https://github.com/shantoroy/linux-sysadmin-cheatsheet/blob/main/scenarios/filesystem-management.md) (Filesystem Management)
