VT100 terminal emulation changing command prompt

I have been able to change the command prompt, and when I type echo $PS1 I get this:

But i got something very different and the command prompt when I first boot up (I don’t start the X window right away, since this is effectively a server).
I looked in .bash_profile and it gives me this:

export PS1="\e[0;34m[\u@\h: \w]$ \em "

What am I doing wrong or what do I need to do to fix this? Thanks

It is not qute clear to me what you did and where. Is this all on 15.0?
How did you change the command prompt to that simple $ (I would do that by editing ~/.bashrc)?

Which .bashrc_profile. I do not have a ~/.bash_profile? Thus who created it?
Where (or when) did you get that “very different one”?

In other words please explain what the difference is between the situations where it works as intended and when not.

Below you see what my default PS1 is (in bash) and what it shows if I change it to what is in your .bashrc:

henk@boven:~> echo $PS1
henk@boven:~> PS1="\e[0;34m[\u@\h: \w]\$ \e[m "
[henk@boven: ~]$ 

where I must add that the last prompt is in blue.
