CD(1)                   NetBSD General Commands Manual                   CD(1)


NAME

     cd -- change working directory


SYNOPSIS

     cd [directory]


DESCRIPTION

     Since cd affects the current shell execution environment, it is always
     provided as a shell regular built-in.  For more information consult the
     manual page for the shell in use.

     The directory operand 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).


ENVIRONMENT

     The following environment variables affect the execution of cd:

     CDPATH           A colon-separated list of pathnames that refer to direc-
                      tories.  If the directory operand does not begin with a
                      slash (`/') character, and the first component is not
                      dot (`.') or dot-dot (`..'), cd searches for the
                      directory relative to each directory named in the CDPATH
                      variable, in the order listed.  The new working direc-
                      tory is set to the first matching directory found.  An
                      empty string in place of a directory pathname represents
                      the current directory.  If the new working directory was
                      derived from CDPATH, it will be printed to the standard
                      output.

     HOME             If cd is invoked without arguments and the HOME environ-
                      ment variable exists and contains a directory name, that
                      directory becomes the new working directory.

     OLDPWD           Set to the previous working directory after a directory
                      change.  Not supported by csh(1).

     PWD              Set to the current working directory.


EXIT STATUS

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

     ble.
