All you have to do is replace all occurances of 'cd' in the shell program
with some new name.  I used my editor to do this, but most editors can't
handle ascii files so I made a simple program to do it.  The new name for the
command I picked is 'ce'.  Originally I tried 'Cd' but that didn't work.  I
think either it doesn't like the command being in uppercase, or the commands
are sorted.  'ce' is in the same sort position as 'cd' and it works.

1) compile this program to 'a.out'

	main()
	{
	int c;
	while(-1!=(c=getchar()))
	 if(c!='c') putchar(c);
	 else
	  {
	  c=getchar();
	  if(c=='d') putchar('c'), putchar('e');
	  else putchar('c'), putchar(c);
	  }
	}

2) Now run the program and make a new shell (it would not be a good idea to
   replace sh)

	cat /bin/sh | a.out >/bin/jsh
	chmod a+x /bin/jsh

   (jsh for Joe's shell, of course :-)

3) now change your shell to the new shell in the password file and put this
   in your .profile

	cd () { ce $*; PS1=`pwd`">"; }
	cd
