a separate cd utility would have no effect (it would change

shells may implement cd with features different from

represents the current directory. If the new working directory
was derived from CDPATH, it will be printed to the
See sh(1) for details. Users of csh(1) use
HOME If cd is invoked without arguments and the HOME environment variable
exists and contains a directory name, that directory becomes
the new working directory.
