Forwarded CMD.EXE commands

Nu accepts and runs some of CMD.EXE's internal commands through cmd.exe.

The internal commands are: ASSOC, CLS, ECHO, FTYPE, MKLINK, PAUSE, START, VER, VOL

These internal commands take precedence over external commands.

For example, with a ver.bat file in the current working directory, executing ^ver executes CMD.EXE's internal VER command, NOT the ver.bat file.

Executing ./ver or ver.bat will execute the local bat file though.

Note that Nushell has its own start command which takes precedence. You can call the CMD.EXE's internal START command with the external command syntax ^start.
