NAME
	  cd - Changes the current working directory

     SYNOPSIS
	  cd [directory]


     DESCRIPTION
	  The cd command moves you from	your present directory to
	  another directory.  You must have execute (search) permis-
	  sion in the specified	directory.

	  If you do not	specify	a directory, cd	moves you to your
	  login	directory ($HOME in ksh	and sh environments, or	$home
	  in csh environment).	If the specified directory name	is a
	  full pathname, it becomes the	current	working	directory.  A
	  full pathname	begins with a /	(slash)	for the	root direc-
	  tory,	with a .  (dot)	for the	current	working	directory, or
	  with a ..  (dot dot) for the parent directory.  If the
	  directory name is not	a full pathname, cd searches for it
	  relative to one of the paths specified by the	$CDPATH	shell
	  variable (or $cdpath csh variable).  This variable has the
	  same syntax as, and similar semantics	to, the	$PATH shell
	  variable (or $path csh variable).

     EXAMPLES
	   1.  To change to your home directory, enter:

	       cd



	   2.  To change to a new directory, enter:

	       cd  /usr/include



	       This changes the	current	working	directory to
	       /usr/include.  Now file pathnames that do not begin
	       with / or ../ specify files located in /usr/include.

	   3.  To go down one level of the directory tree, enter:

	       cd  sys



	       If the current working directory	is /usr/include	and if
	       it contains a subdirectory named	sys, then
	       /usr/include/sys	becomes	the current working directory.

	   4.  To go up	one level of the directory tree, enter:

	       cd  ..



	       The special filename .. (dot dot) always	refers to the
	       directory immediately above the current working direc-
	       tory.
