NAME
       cd - Change working directory

SYNOPSIS
       cd ?dirName?
_________________________________________________________________

DESCRIPTION
       Change the current working directory to dirName, or to the home directory (as specified in the HOME environment variable) if dirName is not
       given.  Returns an empty string.  Note that the current working directory is a per-process resource; the cd  command  changes  the  working
       directory for all interpreters and (in a threaded environment) all threads.

EXAMPLES
       Change to the home directory of the user fred:
	      cd ~fred

       Change to the directory lib that is a sibling directory of the current one:
	      cd ../lib
