Odd behaviour when example.sh is invoked with no args about bash3boilerplate

[gdevenyi]

Not sure what you're referring to here, HEAD doesn't do that:

$ git clone [email protected]:kvz/bash3boilerplate.git

What version of bash are you using? bash --version

[gdevenyi]

It looks like you had a debug mode enabled on your terminal somehow.

@gdevenyi they set PS4 and turned on -x: qwertyzw% PS4='Line ${LINENO}: ' bash -x ./example.sh so they are intentionally showing us the output.

@QwertyZW what is the problem? You expect the help text to print when invoking ./example.sh but it doesn't?

Thanks for the fast response guys.

@zbeekman yep, this is what I was looking for
