The only TRULY foolish question is the one that was not asked!

Most UNIX shells have the concept of multiple prompts. Most notable of
those are:
(1) At the command line
(2) When at an extended line from the command line

These are represented by the environment variables PS1 and PS2
respectively.

With ksh and bash these *can* be evaluated when they are displayed to
give them a dynamic feel. Bash has extensions to the functionality that
ksh provides.  The bash man page/info file will provide the full
documentation. But the short answer to your question is:

MSDOS 'prompt $p$g'  is equivalent to export PS1='\w >'

A more typical setting would be '\h \w >' . The \h provides the host
name.  I usually use something like: export PS1=$(uname -n)'-$PWD->'

Note that the $(uname -n) is eval-ed when the variable is assigned
whereas the hard-quoted '$PWD' is evaluated when displayed.  This way I
figure out what machine I am on only once. And it is compatible with ksh
(under different platforms).

I hope that helps!
