As hex4def6 said, the idea was that DOS command conflicts are not a good idea, while overriding PowerShell builtins in interactive sessions (PSReadLine) is acceptable, if not a good idea. We open-sourced DOS sort and published a port of the DOS find command. The suite then dispatches to the GNU/DOS variant based on heuristics.

Echo doesn't conflict with the DOS command?

[lhecker]

Yup! echo is a CMD builtin and doesn't exist as a dedicated executable.

Sorry, I'm not following the logic. Isn't the same true for dir?

[lhecker]

...huh, true. It's weird what kind of mistakes one can do sometimes. This one was almost comically on the nose.

Is there a list of CMD builtins somewhere?
