NAME    [Toc]    [Back]

       cd - Changes the current working directory

SYNOPSIS    [Toc]    [Back]

       cd [directory]


       The  C shell  has a built-in version of the cd command. If
       you are using the C shell, and want to guarantee that  you
       are using the command described here, you must specify the
       full path /usr/bin/cd.  See the csh(1) reference page  for
       a description of the built-in command.

STANDARDS    [Toc]    [Back]

       Interfaces  documented  on  this reference page conform to
       industry standards as follows:

       cd: XCU5.0

       Refer to the standards(5) reference page for more information
 about industry standards and associated tags.

OPTIONS    [Toc]    [Back]


OPERANDS    [Toc]    [Back]

       The  pathname  (either full or relative) to be used as the
       new working directory.

              If  (hyphen) is specified as the directory, the  cd
              command changes your current (working) directory to
              the directory name saved in the  environment  variable

DESCRIPTION    [Toc]    [Back]

       The  cd  command  moves you from your present directory to
       another directory.  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 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 directory, 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).

EXIT STATUS    [Toc]    [Back]

       The following exit values are returned:

       The   directory   was   successfully  changed.   An  error

EXAMPLES    [Toc]    [Back]

       To change to your home directory, enter: cd 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.  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.
  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


       The  following  environment variables affect the execution
       of cd: A colon-separated list of pathnames that  refer  to
       directories.  If the directory operand does not begin with
       a / (slash) character, and  the  first  component  is  not
       (dot)  or cd command will search for directory relative to
       each directory named in the CDPATH variable, in the  order
       listed. The new working directory will be set to the first
       matching directory found. An empty string in  place  of  a
       directory  pathname  represents  the current directory. If
       CDPATH is not set, it will be treated as  if  it  were  an
       empty  string.   The name of the home directory, used when
       no directory operand is  specified.   Provides  a  default
       value  for  the  internationalization  variables  that are
       unset or null. If LANG is unset or null, the corresponding
       value  from  the  default  locale  is used.  If any of the
       internationalization variables contain an invalid setting,
       the  utility  behaves as if none of the variables had been
       defined.  If set to a non-empty  string  value,  overrides
       the  values  of  all  the other internationalization variables.
  Determines the locale for  the  interpretation  of
       sequences  of  bytes of text data as characters (for example,
 single-byte as opposed  to  multibyte  characters  in
       arguments).  Determines the locale for the format and contents
 of diagnostic messages written  to  standard  error.
       Determines the location of message catalogues for the processing
 of LC_MESSAGES.  A pathname of the previous  working
  directory, used by the cd - form of the command.  The
       cd command sets this  variable  to  your  current  working
       directory  before  changing to a new current directory.  A
       pathname of the current working directory, set by  the  cd
       command after it has changed to that directory.
