IF you source a script the environment variables persist. A sourced script should not call exit or you will be logged out.
Two ways to source a script named env.sh
Those tools probably had you running inside a child process, with the parent process killed off. So when you exit the now-current child process, you log out.
Another more sensible approach: In C/perl you can all exec to run a command like "bash -c env.sh" to set variables. Which is probably what the perl code did. This does not create a child it replaces the old process. This is also what sourcing does.
