        Usage: cd [OPTIONS] [--help]

        Move into new context (object or scope). As in UNIX shells use `cd ..` to go
        back, `cd /` to return to Pry top-level and `cd -` to toggle between last two
        scopes. Complex syntax (e.g `cd ../@x/@y`) also supported.

        cd @x
        cd ..
        cd /
        cd -
