Ubuntu Commands

Personal Linux / Ubuntu command and tool cheat-sheet notes. Organized by topic; each subdirectory contains a readme.md (or an equivalent index file).

Quick Start

• commands.md — most-used commands + category index
• cheatsheet/ — system / files & disk / network & SSH / text processing / tmux-cron-docker / dev config
• rufus — make a bootable Linux install USB (the first step before installing Linux, on Windows)

Categories

Install Media / Bootable USB

• rufus — flash a Linux .iso onto a USB stick (Windows; portable, no install). On Linux you need no extra tool — dd / gnome-disks already do this.

Privacy

Placeholders such as <USER>, <SERVER_IP>, <YOUR_HOME>, <YOUR_EMAIL>, <YOUR_GITHUB>, <YOUR_DOCKERHUB>, <HOSTNAME>, <NAS>, <PRIVATE_IP> are redacted. The original private data (intranet IPs, emails, usernames, private paths) has been scrubbed.

Maintenance

• To add a new topic, create a lowercase folder at the repo root (e.g. lower_snake) with a readme.md inside.
• General high-frequency commands live in commands.md; topic details go under cheatsheet/.
• Editor backup files (*~, *.swp, *.bak) are ignored by .gitignore; do not commit them.
