After Bill answered I saw this in a "bash" FAQ at:

G5) How do I get the current directory into my prompt?

Bash provides a number of backslash-escape sequences which are 
expanded when the prompt string (PS1 or PS2) is displayed.  The full 
list is in the manual page.

The \w expansion gives the full pathname of the current directory, 
with a tilde (`~') substituted for the current value of $HOME.  The 
\W expansion gives the basename of the current directory.  To put the 
full pathname of the current directory into the path without any 
tilde subsitution, use $PWD.  Here are some examples:

	PS1='\w$ '	# current directory with tilde
	PS1='\W$ '	# basename of current directory
	PS1='$PWD$ '	# full pathname of current directory

The single quotes are important in the final example to prevent $PWD 
from being expanded when the assignment to PS1 is performed.
