[Wrapper-user] Contribution: smaller fixes for test wrapper script (unix)

[Dannes W. <di...@ex...>]

Hi,

please find attached a modified version of the unix test wrapper script, containing some smaller modification to have the script better working for MacOSX (and a typo fix)

I have the changes in use for a long time now, I'd like to contribute by ideas and hope you can use it.

Kind regards

Dannes
