cd(1)                            DG/UX R4.11                           cd(1)


NAME
       cd - change working directory

SYNOPSIS
       cd [ directory ]

DESCRIPTION
       If directory is not specified, the value of shell parameter $HOME is
       used as the new working directory (also $home in csh).  If directory
       specifies a complete path starting with /, ., or .., directory
       becomes the new working directory.  If neither case applies, cd tries
       to find the designated directory relative to one of the paths
       specified by the CDPATH shell variable ( cdpath in csh).  $CDPATH has
       the same syntax as, and similar semantics to, the PATH shell variable
       ( path in csh).  Cd must have execute (search) permission in
       directory.

       Because a new process is created to execute each non-built-in
       command, cd would be ineffective if it were written as a normal
       command; therefore, it is a built-in command for both the Bourne
       shell and the C shell.

EXAMPLES
       $ pwd
       /usr/user1
       $ cd workdir
       $ pwd
       /usr/user1/workdir
       $

       The above example changes your current directory to the directory
       named "work_dir."  "Work_dir" is located below the directory
       /usr/user1.  The string, "..", can be substituted to indicate the
       directory above the current directory.  This string can be repeated
       on the same command line to go up several levels.

DIAGNOSTICS
       Exit code is 0 on successful completion, and >0 if an error occurs.
