ps1

Is there any way to 'evaluate' PS1, PS2, etc from within a bash script?

Although, I can use alternate means to get all elements of my current PS1, I would really like to be able to reuse its definition instead of using these alternate means.

For example,

=====================================
 PS1 element -->     Alternate means
=====================================
 \u          -->     $USER
 \h          -->     $HOSTNAME
 \w          -->     $PWD
 ...
=====================================

I could very well use the 'alternate means' column in my script, but I don't want to. In my PS1, I, for example, use bold blue color via terminal escape sequences which I'd like to be able to simply reuse by evaluating PS1.
