The quickest way I’ve found is to use the “windows software distribution” wizard.
Walk through the wizard and the most important part is the that it uploads the file and creates the action to push it to the endpoint.
Once it is created then you can edit the relevance to target Linux only and change the action from something like:
copy somefile.txt /path/to/somefile.txt
Hope this helps.
