I missed this when it was first posted and I ended up doing something related without actually realizing it. I created an install_bigfix.sh script to make it very easy to install BigFix on Linux/Unix/Mac. I then realized that it could be used to install BigFix in Docker containers and created docker_bigfix_client.sh to do so.
I structured my script to be a single monolithic one so that it could be downloaded as a single unit and executed, but otherwise there are many similarities.
