Hello, I'm starting with the cygwin recently and due my lack of
knowledge I have this basic/fool question:
When a I run Cygnus form Windows98 the prompt stay fixed at
BASH.EXE-2.02$
How can I set it like the "prompt $p$g" command of MS-DOS ?
Thank you.
Leonard

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!

It's documented in the bash manual. You have to change the PS1 and PS2
variables. Have a look at `Printing a Prompt' in section `Bash Features'
as well.
