My two thoughts are: 1. Approach it similar to [here](https://github.com/anandsubbu/incubator-metron/blob/dc3fa9739bad53da7931d992cdfd499abba5387d/metron-deployment/scripts/platform-info.sh#L68), using a `case "${OSTYPE}"` to watch `darwin*` and `linux*`, and then a `*)` that alerts the user. 1. By adding an elif for either `"${OSTYPE}" == linux*` or `"${OSTYPE}" =~ "linux"`, and then an `else` that alerts the user.
