Generador de prompts de script bash
Used by developers, writers, and creators worldwide.
A bash script prompt generator builds a careful, fill-in request you can hand to an AI assistant so it writes a script that fails safely instead of silently corrupting things. Describe what the script should do and say whether it takes arguments, and it produces a prompt that demands a strict shebang, set -euo pipefail, quoted expansions, a usage function and help flag, argument validation or documented environment variables, logging to stderr, and a cleanup trap. Developers use it to get production-grade scripts from a model, avoid the unquoted-variable bugs that plague shell code, and standardise how their team writes automation. It runs in your browser and generates instantly. Edit the task and toggle whether the script accepts arguments, then paste the prompt into your assistant. The strict requirements steer the model away from fragile one-liners that break when a path contains a space.

Use Cases
- •Getting a robust, shellcheck-clean script from an AI assistant
- •Avoiding unquoted-variable and error-handling bugs
- •Standardising script structure across a team
- •Scaffolding a backup, deploy, or maintenance script
- •Teaching safe bash conventions to newer engineers
Tips

- →Ask for a dry-run flag on anything destructive.
- →Test on a copy before pointing the script at real data.
FAQ
why require set -euo pipefail
Those options make the script exit on errors, on unset variables, and on failures inside a pipeline. Without them, a failed command is silently ignored and the script charges ahead, which is how shell scripts cause real damage.
why a trap on EXIT
A trap guarantees cleanup of temporary files and locks even when the script exits early or hits an error. It is the shell equivalent of a finally block and prevents the litter that accumulates from interrupted runs.
will the script be portable
The prompt asks for POSIX-friendly constructs where reasonable, but bash-specific features are allowed since the shebang targets bash. If you need strict POSIX sh, add that to the prompt before sending.
