depending on whether the status code of the last command was good or
bad. I found this surprisingly useful. They use:
\[`if [ $? = 0 ]; then echo "\e[32m"; else echo "\e[31m";
fi`\]\w[\e[0m\]>
(or, as another example, just a fat red $? if it's != 0,
PS1='\[\e[0;1;31m\]${?#0}\[\e[30m\]\w \[\e[0m\]'
which I've gotten really dependent on over the years)
