Cheat Sheets

Every command from Terminal Practice, grouped by job, with what it does. Each sheet prints cleanly in black and white.

• Linux Commands Everyday Linux commands for Ubuntu/Debian and Rocky/Red Hat. Pipes (|), redirects (> and >>), && and * wildcards work with all of them.
• PowerShell Commands Windows PowerShell cmdlets. They pass objects down the pipeline (|), so you can filter, sort, and pick properties.
• Command Prompt Commands Windows Command Prompt (cmd.exe). Options start with / (dir /s, ipconfig /all), and commands are not case-sensitive.
• Cisco IOS Commands Cisco IOS for Catalyst switches and ISR routers. Any unique abbreviation works (conf t, sh ip int br), and ? lists what can come next.
