cd(1)                      (Essential Utilities)                      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 /, ., 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 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 by and is internal to the shell.
