cd

PURPOSE

     Changes the current directory.

SYNOPSIS
     cd [ directory ]


DESCRIPTION

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

     If you do  not specify a directory, cd moves  you to your
     login directory ($HOME).  If the specified directory name
     is a full path name, it becomes the current directory.  A
     full path name begins with a "/" (slash--root directory),
     with a "." (dot--current directory),  or with a ".." (dot
     dot--parent directory).   If the directory name  is not a
     full path name, cd searches for it relative to one of the
     paths specified by the $CDPATH shell variable.  This var-
     iable has the  same syntax as, and  similar semantics to,
     the  $PATH shell  variable.   (See  "Shell Variables  and
     Command-Line  Substitutions"  for  a discussion  of these
     variables.)

EXAMPLES

     1.  To change to your home directory:

           cd

     2.  To change to an arbitrary directory:

           cd  /usr/include

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

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

           cd  sys

         If the current directory  is "/usr/include" and if it
         contains   a    subdirectory   named    "sys",   then
         "/usr/include/sys" becomes the current directory.
     4.  To go up one level of the directory tree:

           cd  ..

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

     Note:   The csh  command contains  a built-in  subcommand
     named cd.  The command  and subcommand do not necessarily
     work the  same way.   For information on  the subcommand,
     see the csh command.
