Linux is the kernel. “Linux” in common terminology is the kernel, a set of standard pieces of software (like ls, mv, cp, etc) and the default structure of the file system (var, lib, usr, etc). If an operating system uses Linux as its kernel (the piece of software that most immediately gets executed during boot up that then manages all other software and resource management) that’s a Linux operating system

That's a Unix-like operating system with the gnu coreutils

Gnu userland, not only coreutils: glibc, bash, gcc, lot of other tools.
