Error handling in Bash scripts requires implementing strict mode, error trapping, and validation to catch failures gracefully and prevent silent execution issues. This approach ensures scripts halt on errors and manage unexpected failures robustly.

The best way to make Bash automation scripts safe for CI/CD pipelines is by applying defensive programming techniques like strict variable safety, error trapping, and idempotent design. These practices ensure high reliability during complex deployment workflows.

Implement cleanup procedures in shell scripting by using error traps to execute teardown commands when a script fails or exits unexpectedly. This ensures temporary files are removed and resources are released safely.

You need strict mode and variable validation in Bash script design whenever you are automating system administration tasks or building deployment workflows that require high reliability. These fault-tolerance strategies prevent undefined variables and unhandled errors.

A Bash script continues running after a command fails because error handling is not enabled by default. You must manually implement strict mode and error trapping to ensure the script exits immediately when a command returns a non-zero status.
