Yes, I've been experiencing such inconveniences. On the other hand, having 
the path starting from the "~" sign (or the topmost "/") down to the 
current directory is quite helpful for knowing where one is at the current 

Now I've recalled that I did something for that under Linux. There was 
some reason to do the resettings in .bashrc rather than in .bash_profile. 
So, under Linux, I see that I have in .bashrc

# Set the prompter.
export PS1='\u@\h \w\$> '

Then .bash_profile calls .bashrc by including the following lines in it:

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
         . ~/.bashrc

I have such .bash_profile under OS X 10.4 too, just for a couple of 
aliases warning for rm and mainly for setting the PATH:

export PATH=$PATH:$HOME/bin

I guess something like the above for Linux should be set in Leopard, 
if one wants a detailed prompt. Despite of the inconvenience that Bruno 
explains, I find the prompt showing the path to the current directory 
practical and most likely would like to set it up under Leopard (hoping 
that the upgrade will go finely...).

Hm, may be you are right and I should just try to work with the default 

Do we need to set up the PATH, with export PATH=$PATH:$HOME/bin
(as we do in 10.4) in Leopard?
