The Functional Tao of Bash
summary
Claims Bash isn’t a functional language but functional techniques apply: the presenter refactors a 140‑line CI.sh, extracts blocks into named functions, replaces ad‑hoc globals and ugly conditionals with clear interfaces, and shows patterns like generators with find | xargs, pushd/popd, and guarded args plus set -euo pipefail. A separate parallel script is built as a safer replacement and verifies behaviors (it runs and clarifies intent), not just examples.
