This kinda happened in the UNIX world: https://en.wikipedia.org/wiki/C_shell https://en.wikipedia.org/wiki/C_shell

  Kinda, except that C shell syntax isn't very C language like. I think 8 bit micros (Apple II, Commodore 64) are closer. They booted up into BASIC and their DOS was an extension to BASIC.

    I like to say their OS shell was also an IDE.

    The DOS for the Commodore computers including the above mentioned Commodore 64 was not an extension to BASIC. The DOS for Commodore computers instead ran on the floppy drive units themselves which included their own RAM and 6502 family CPUs to do so. The other 8-bit micro I used personally was the TRS-80 Model 1. It would boot directly to BASIC but their was no DOS as part of this basic. To use a floppy drive a DOS boot disk was required. There were a few different DOS's available for the machine. The official DOS available from Tandy was TRS-DOS.

      Regardless of where it ran, to the C64 user, at a command level, it looked and acted like an extension to BASIC. You can see some examples of the basic code here: https://en.wikipedia.org/wiki/Commodore_DOS https://en.wikipedia.org/wiki/Commodore_DOS Apple ProDOS had similar stuff...

  TempleOS is written in a custom language inspired by C and C++ called HolyC. And HolyC is used as the shell. So that's actually much closer to what you are talking about than any Unix shell is (C shell included)
