Prompt changing on the fly - Oops

Later that same day:

Oops, it is possible in the Bourne shell.  What you can do
is define a function (not well known in the Bourne shell)
to do your cd's and set PS1.

chdir()
{
    case ${#} in
	1) cd $1 && PS1="`pwd` "
	   ;;
	*) echo "usage: chdir directory" >&2
	   return 1
	  ;;
    esac
}

Now just use chdir instead of cd. 

In the Korn Shell, you can do something like:

PS1='${PWD} '

This works because PS1 is *evaluated* every time it is printed.
You can use cd and PS1 is updated automatically.
