[Bas]

Is your feature request related to a problem? Please describe.
The output from the scripts is all over the place.
Maybe make a standard with functions an a consistent echo.

Describe the solution you'd like
Create an sh file with default print functions.
Editing all the test scripts.
This needs to be done.

Describe alternatives you've considered
If you do not create a default script.
If the change is not liked, you need to edit all the echo's and other functions.
