- #
- # The Unofficial "Bash Strict Mode"
- # -e Failed commands exit
- # -u Unbound variables exit
- # -o pipefail Do not hide piped-command failures
- # IFS as newline and tab are better for loops (and name with spaces).
- #
- # Tips:
- # - Options can be switched off and on as required:
- # - Toggle `-e` if previous command's return value is needed (`$?`).
- # - Toggle `-u` if sourcing another non-conforming script.
- # - Use default values for positional parameters i.e. `${1:-}`.
- # - Intentionally undefined variables should be set to "" rather than not set.
- # - Learn about "exit traps" to perform `try-catch-finally`-like cleanup tasks

- set -euo pipefail
