bash

My favorite shebang

#!/usr/bin/env -S bash -euo pipefail

-S

--split-string: process and split S into separate arguments; used to pass multiple arguments on shebang lines

-e

errexit, exit immediately if a command fails

-u

nounset, treats unset variables as an error

-o pipefail

prevents errors in a pipeline from being masked

-x

Print a trace of simple commands
