NAME
       cd - change working directory

SYNOPSIS
       cd directory

DESCRIPTION
       Directory becomes the new working directory.  The process 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.  It is therefore
       recognized and executed by the Shell.

SEE ALSO
       sh(1), pwd(1), chdir(2)
