                          Basically, I used the native Safari.app web browser to download a third party application and I want to run / open it from the comfort of my bash shell / Terminal.app CLI; despite the following error message:

    “” can’t be opened because it is from an unidentified 
     developer. Your security preferences allow installation of only apps from the Mac 
     App Store and identified developers. Safari downloaded this file on  
     from .
                                              |[OK]|
