since Mountain Lion still uses the old bash 3.x, I was wondering if there is a good tutorial (or if somebody could post one here) on how to upgrade bash to the latest version. Also, it would be helpful to know how to set the path so that it can be used in terminal.
Thanks in advance

- Update brew:
brew update - Install bash with
brew install bash - Add
/usr/local/bin/bashto/etc/shells - Change the default shell with
chsh -s /usr/local/bin/bash
You don't normally have to change any settings in Terminal or iTerm 2. Both of them default to opening new shells with the default login shell.
