atf-sh is an interpreter that runs the test program given in script after loading the atf-sh-api(3) library.
atf-sh is not a real interpreter though: it is just a wrapper around the system-wide shell defined by the ‘atf_shell’ configuration value in atf-config(1). atf-sh executes the interpreter, loads the atf-sh-api(3) library and then runs the script.
Scripts using atf-sh-api(3) should start with:
#! /usr/bin/env atf-sh
