For the future "you" 🫵 to keep on enjoying GNU Bash.
For many decades now,
we've had an unofficial Bash strict mode
(Reddit),
essentially set -euo pipefail.
Except GNU Bash evolved - errtrace functrace inherit_errexit
and then there's one last thing (tm): stack trace on failure.
sane.bash wraps all that up in a script to import (source) or simply copy-paste since a little copying is better than a little dependency .
docs-sane.bash is the same code but with inline documentation.
reference-sane.bash is the same code,
minus the documentation, compact, adding argument parsing,
acting as a full reference/template for a copy-paste approach instead of sourcing.
Have a look at the example and example-inline for usage and docs.
