Before Rsh version 0.67, Rsh
used to
use CMD.EXE to launch external commands, which meant that the
above builtins could be run as an
^external command. As of version 0.67, however, Rsh
no longer uses CMD.EXE to launch externals, meaning the above
builtins cannot be run from within Rsh, except for
ASSOC, DIR, ECHO,
FTYPE, MKLINK, START,
VER, and VOL, which are explicitly
allowed to be interpreted by CMD if no executable by that name
exists.
