Bash Linux

A solid reference card for bash essentials that covers what you actually need when working in the terminal. You get operator chaining, file operations, process management, and text processing tools in quick-reference tables. The script template with error handling flags (set -euo pipefail) is genuinely useful, and the PowerShell comparison table helps if you're coming from Windows. It's not trying to teach bash from scratch, just giving you the commands and patterns you'll reach for when debugging a process, grepping logs, or writing a deployment script. Keep it open when you need syntax you use monthly but can never quite remember.
