Secure Bash scripting relies on strict conventions like `set -Eeuo pipefail` and `shopt -s inherit_errexit` to catch errors early. It also involves avoiding `eval` to protect against command injection and using trap pairs for reliable resource cleanup.
Error handling in Bash uses a standard `die()` function paired with a trap to catch failures and execute cleanup routines. This guarantees that temporary files and resources are removed even when scripts abort unexpectedly.
Linting Bash scripts with shellcheck identifies unsafe code patterns, while shfmt enforces consistent formatting. Together, they analyze scripts for security vulnerabilities and automatically format code to adhere to strict tooling standards.
Using `[[ ]]` over `[ ]` in Bash control flow prevents word splitting and pattern matching errors. It is the idiomatic standard for writing robust, modern shell scripts that handle string dispatch securely.
Bash scripting works seamlessly with bats-core to execute automated unit tests. Organizing your project with a dedicated `test/` directory allows you to validate script behavior and ensure code quality before deployment.
