# Bash Defensive Patterns

Write shell scripts that fail loudly instead of silently

## What this does

Shell scripts tend to keep going after something has already gone wrong, and the damage shows up later. Defensive Bash is the set of habits that make a script stop, check, and clean up instead. Reach for it when a script is going to run unattended - in CI, or as a system utility.

### Top 3 things it does for you

- Write a shell script that holds up in production
- Add fault tolerance to a CI/CD pipeline script
- Harden a system utility against bad input

## Questions

### Is Bash Defensive Patterns safe to install?

AIR scanned this exact version of Bash Defensive Patterns and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit be57c0b2e3c0, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/bash-defensive-patterns.
