On reprends les tips 👍

Juste après le « shebang », mettre ça sur la ligne d’après :
set -euo pipefail

• set -e which ensures that your script stops on first command failure.
• set -u which ensures that your script exits on the first unset variable encountered.
• set -o pipefail which ensures that if any command in a set of piped commands failed, the overall exit status is the status of the failed command.
