Is there a command working on BOTH linux and mac OS for determining the OS version? [duplicate]

Question

I know there is, for example, hostnamectl command on linux and system_profiler SPSoftwareDataType command on macOS to know the operating system version, but I'm looking for a command that works for both operating systems. Does it exist?

uname -v is probably the closest you can get. Its output, though, isn't particularly standardized. — chepner

I use uname -s with tr inside Makefile to determine the system and decide whether to use .so od .dylib.

On macOS

> uname -s | tr '[:upper:]' '[:lower:]'
darwin

On Linux

> uname -s | tr '[:upper:]' '[:lower:]'
linux
