Linux Shell Scripting

This is a collection of ready-to-use bash templates for the Linux sysadmin tasks you run into constantly: automated backups with rotation, CPU and disk monitoring with configurable thresholds, user account management, log parsing, and basic security utilities like password generation and file encryption. The scripts are straightforward, not over-engineered, and cover the boring-but-necessary stuff like backing up databases, checking website uptime, and analyzing web server logs. Most useful as starting points you can customize rather than production code you'd deploy unchanged. If you're building out automation for a new environment or need reference implementations for common patterns, this gives you a solid baseline without starting from scratch.
