I'm not sure what you mean by that, but I don't think there ARE any commands like that. CMD is a much better "shell" (I guess it's a shell, though I've never heard it called that before) than command.com, but I've found it's still quite limited.
If your "purposes" are anything cool, download cygwin and have some fun learning bash. It's like a linux emulator, but you won't have to worry that it'll mess up anything like a dual-boot *nix/Windows machine (somehow they sense each others presence and destroy each other).
As a former "Windows Only" biggot, it was hard to admit it to myself, but CMD can't do nearly as much as a *nix shell (like bash)
Anyway, here's Cygwin (quick, use bash before anyone tells you a different one to use):
