This is yet another post in which I'm (almost) simply reposting a solution that someone else has already posted online.
Let's say that my contribution is to put it in context of debian.
Either way, here's the problem that needed solving: the debian prompt by default lists all directories, which sometimes means that the prompt itself breaks across two lines.
Luckily, it's not difficult to chop the prompt down to a more manageable, yet still informative, length. The solution is here (we do like a descriptive URL): http://superuser.com/questions/387673/how-can-i-limit-the-number-of-directories-in-my-prompt
That particular solution also allows you to change the permissible length of the path that will be shown -- change the 50 in the argument to droppath to set the number of chars.
Edit your ~/.bashrc and add the bits in red:
and here's an example using a length of 25 chars (which is a bit short).

You can always use pwd to figure out what the full path is if necessary:

This is dummy text. It is not meant to be read. Accordingly, it is difficult to figure out when to end it. But then, this is dummy text. It is not meant to be read. Period.
