Reverse transfer of values from bash to LO macro

Question

I’m a beginner and I’m using in a LibreOffice macro the shell command:

    Shell(Pathname, Windowstyle, Param, bSync)

to activate some bash scripts. Reading the blogs I understand that variables value transfer is one-way, top to down. Is there a way to have back to the calling macro some values, integers or strings, or it is necessary to go throughout a .tmp file? If possible I would like to have some example code.

Thanks to KamilCuk I posted on LibreOffice and I received the answer: there is no way. The only one is using a file!
