Bash function and exiting early

The article details a real-world incident where a service deployment failed silently despite passing health checks. The root cause was a Bash startup script that continued execution after a PHP environment parsing error. The author explains the problem with the script's error handling, experiments with adding `set -e`, encounters issues with `grep` exit codes in pipelines, and considers using `pipefail` to ensure the script fails fast on any command failure.
