     ccdd - change working directory

     ccdd _d_i_r_e_c_t_o_r_y

DDEESSCCRRIIPPTTIIOONN
     The cd utility changes the working directory to _d_i_r_e_c_t_o_r_y.

     The _d_i_r_e_c_t_o_r_y is an absolute or relative pathname which becomes the new
     working directory.  The interpretation of a relative pathname by cd
     depends on the CDPATH environment variable (see below).

EENNVVIIRROONNMMEENNTT
     The following environment variables affect the execution of cd:

     HOME      If ccdd is invoked without arguments, the HOME environment vari-
	       able is checked for a default directory name. If HOME exists
	       and contains a directory name, that directory becomes the new
	       working directory.

     CDPATH    If the _d_i_r_e_c_t_o_r_y operand does not begin with a slash (/) char-
	       acter, and the first component is not dot (.) or dot-dot (..),
	       ccdd searches for the directory relative to each directory named
	       in the CDPATH variable, in the order listed.  The new working
	       directory is set to the first matching directory found.	An
	       empty string in place of a directory pathname represents the
	       current directory.  CCdd will print the pathname of the new work-
	       ing directory if it was an element of CDPATH.  See csh(1) for
	       info on environment variables.

     The ccdd utility exits 0 on success, and >0 if an error occurs.
