You need to have powerline patched fonts installed. Get them here

And you need to configure your terminal to use them. (this ofc depends on your terminal but probably something like settings -> appearance -> fonts)

I've done something similar if you want a startingpoint: sbp You can try it out by running . prompt.bash.

Basically all you need if the fonts are installed and enabled is this $'\uE0B0' somewhere in your PS1. It's the utf8 code for the fancy triangle. Assuming you're on a recent version of bash with some utf8 as locale, that should do it. Try echo -e $'\uE0B0' in your terminal to test it.
