Commands in PC Operating Systems

Can you list common commands in DOS/Windows, Linux, and CP/M?
CP/M counts as a PC operating system because of CP/M-86.
One CP/M command is exclusive to CP/M-86.
All Windows commands are identical to their DOS equivalents.
Bonus: Name the creators of these operating systems.

Shouldn't it be 'cat' instead of 'more' on Linux for displaying a file's content? More is used for display output of a command in pages both on Linux/Windows and other Unix-like operating systems.

Since correcting the answer reset the stats anyway, I've added two more questions.
