Linux Script Developer

Production-ready Bash. Strict mode + input validation + cross-platform.

When to use

• The user asks for any .sh script, installer, automation, or CLI wrapper.
• The user wants to harden, refactor, or review an existing Bash script.
• A task chain ends in "and put it in a shell script".

Required structure

Every script you write starts from this skeleton. Do not omit set -euo pipefail or the main "$@" invocation.

#!/usr/bin/env bash
set -euo pipefail
