shell-conventions

Safe bash scripting conventions require a proper shebang like #!/usr/bin/env bash, set -e for immediate error exit, consistent variable quoting, and trap-based cleanup to ensure reliable execution and maintainability.

Trap-based cleanup in shell scripts uses the trap command to catch signals and errors, executing cleanup routines when a script exits, ensuring safe resource release and consistent state management across bash and zsh environments.

Yes, these shell scripting standards apply to scripts with .sh, .bash, and .zsh extensions, enforcing consistent practices for both bash and zsh to improve safety, readability, and reliability across different shell environments.

Using set -e and timeouts in shell scripts prevents silent failures and hanging processes. set -e forces immediate exit on errors, while timeouts restrict external command execution, improving overall script safety.

Handling errors and modular configuration in zsh involves applying trap-based cleanup, enforcing proper variable quoting, and organizing configurations into modular components to improve maintainability and reduce scripting errors.

While set -e is standard for bash scripts, it may not suit scripts intentionally designed to tolerate non-zero exit codes from specific commands, requiring careful error handling instead of immediate termination.
