Yeah this is OK, but running macOS commands for Linux deployments doesn't work all the time. What about `lsblk` or `ip`? Also md5 vs md5sum. Also and I don't have macOS handy to try it, I'm pretty sure grep has differing options. I can't count how many times friends and colleagues who use macOS for development have put BSD commands into Dockerfiles and CI pipelines and have wondered why it didn't work.

For a (partly compatible) equivalent to ip I can recommend iproute2mac [1]. You can also use the old utilities from BSD (ifconfig, route, etc) or the GUI.
For lsblk I found no drop-in replacement, just equivalents [2]
On top of that, Nix works on Linux and macOS.
