Your example got me thinking about the difference between how the windows shell and Unix shell is designed. Seems like the windows shell knows about extensions, whereas the Unix shell does not

That’s an interesting feature for a shell to have. Thanks!

It's can be traced back to the roots of each OS. Windows has it's heritage in the land of DOS where files had an 8 character name with a 3 character extension and that extension carried meaning for the OS.

Linux being of Unix ancestry which had no such concept as a file extension. It was the responsibility of the application or kernel to discern what type a file was. Typically by the first few bytes of a file and handle it appropriately.

I personally am a fan of the Unix way but I can see why some might prefer the DOS convention.

Speaking of heritage... 8+3 goes back at least to DECSystem-10 on PDP-10s.

Everything goes back to the PDP-10 we are all using the incestuous off-spring of DEC.

Whether that is good or bad is left as an exercise to the reader.

A lot of it came from RSX11 features that got rolled into the PDP-10 OSes.
