I'm not a .bashrc guru, but here's where I turn:
1. https://wiki.archlinux.org/index.php/Color_Bash_Prompt
2. http://wiki.gentoo.org/wiki/Bash
3. For a good short introduction of prompt basics for all shells,
http://www.understudy.net/custom.html
4. The "prompting" section of the bash manpage for an explanation of the
arcane symbolism of the bash prompt string syntax
As to the line 16 and 18 variables, I don't find them useful unless
you are setting up a lot of different users. Otherwise, to me,
they just add an unnecessary layer.
Here's mine:
PS1="\[\033[01;32m\]\u@\h\[\033[01;34m\] \w \$\[\033[00m\] "
export PS1
Enjoy!
