CD(1)                                                       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.  If directory
          specifies a complete path starting with /, ., .., 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
          has the same syntax as, and similar semantics to, the $PATH
          shell variable.  cd must have execute (search) permission in
          directory.

          Because a new process is created to execute each command, cd
          would be ineffective if it were written as a normal command;
          therefore, it is recognized and is internal to the shell.
