[expert] getting "set prompt=$p$g" functionality in bash

[Andy Thomas]

Hi,
Where would I put the Linux equivalent to the above dos statement in order
to get a prompt showing the current directory ($p) and the greater than
($g) symbol?  Is there some documentation as to all of the options I can
put into my bash prompt?

Without the currentdir in my prompt, it's disorienting at times.  

I believe I asked this on [newbie] awhile back but never heard anything.

TIA
Andy
