Mh… je ne connaissais pas cette astuce.

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.
