So, I followed this tutorial...
It seems that it worked fine. When I type in
echo $SHELL and echo $BASH_VERSION
"/usr/local/bin/bash" and "4.0.0(1)-release" .
But, when I simply run "
bash" I get shells command line with "
bash-3.2$" (not sure if this is important?) and when I try to install RVM (which is my main reason for doing the upgrade in the first place) I still get the
BASH 3.2.25 required (you have 3.2.17(1)-release)
