Ah, it's getting there. It now types over anything added to the second drop down line rather than just continuing on.
jacatone@Dell-4550 ~$ 54df5dddddddddddddddddddddddddddddddddddddddddddddddddddd
222222dddddddddddddd
should be,
jacatone@Dell-4550 ~$ 54df5dddddddddddddddddddddddddddddddddddddddddddddddddddd
dddddddddddddd222222

Oh, sorry mate. I was too tired last night. :)
Let's see...
The colors aren't properly escaped.
Variable expansion and the \[ \] escapes around them make them not count as character positions and the cursor position is not wrong.
This is the proper way to do it:
\[\e[1;31m\]foo
or
\[\e[1;31m\]\[$variable\]
If you want to set it up like this
jacatone@Dell-4550:~$ command...
--- Code: ---export PS1="\[\e[1;31m\]\[\u@\h:\w\$\] \[\e[0m\] "
--- End code ---
You could also set it in two colors
jacatone@Dell-4550: ~$
--- Code: ---export PS1="\[\e[1;31m\]\[\u@\h\] \[\e[0;32m\]\[\W\$\] \[\e[0m\] "
--- End code ---
From your first example I thought you were going to use the [ ] brackets:
[jacatone@Dell-4550~]$
--- Code: ---export PS1="\[\e[1;31m\][\u@\h\w]\$ \[\e[0m\] "
--- End code ---

Actually, I meant after the $ sign then drop down below to the next line like it would if I didn't add any color.
jacatone@Dell-4550:~$ 64dfg646df4g654fg654d6fg64fd64g6fd4g64fd64g6df4g6fd

export PS1="\[\e[1;31m[\u@\h \W]\$ \e[m "
--- End quote ---
If you want to move the prompt sse the \n switch at the end
--- Code: ---export PS1="\e[1;31m[\u@\h \W]\$ \e[m \n"
--- End code ---
