Ok yes, point taken, I just meant it as a general expression. I don't mean to imply that it's exclusive to Linux, although I do specifically prefer the GNU flavor of most of the tools (awk an exception where there are multiple interesting implementations), which do tend to be more closely associated with Linux than macos or BSD. A standard installation of any Linux distro will have them all available, whereas in Mac and Windows you have to specifically install them as they aren't part of the standard command line.
Macos does not come with the GNU utilities. You have to explicitly install them if you want them on macos. The included versions are BSD and similar licensed and are not all compatible with the GNU versions.
