How to fix Terminal not loading ~/.bashrc on OS X Lion [closed]
Terminal opens a login shell. This means, ~/.bash_profile will get executed, ~/.bashrc not.
The solution on most systems is to "require" the ~/.bashrc in the ~/.bash_profile: just put this snippet in your ~/.bash_profile:
[[ -s ~/.bashrc ]] && source ~/.bashrc
Renaming .bashrc to .profile (or soft-linking the latter to the former) should also do the trick. See here.
