Problem with that is that it sets the prompt to whatever the CWD was when you
typed PS1="`pwd`...". In other words, it does not get updated every time you 
cd to a different directory.

Some versions of the Bourne shell maintain a variable $PWD which gets updated
every time you cd, and if that's true for your version of the shell, 

	PS1="\$PWD >";export PS1

will create a prompt that is updated every time you cd.

I have seen other variable names uses for this purpose; to find out what
variable tu use on your system type "set", then "cd ..", then "set" again, and
check which variables reflect this change in your current directory. One other
name I've seen used for this is $CWD, or $cwd on BSD systems.
