These are personal bash configurations, aliases, and other tweaks. You are welcome to use and extend them as you see fit.
To use this bash configuration, copy bash_ext to your home directory (add a '.' in front) and add the following line to the bottom of your ~/.bash_profile:
. ~/.bash_ext || echo "*** Unable to load bash ext. Profile settings are offline."
The next time your bash profile is loaded (such as opening a new terminal session or logging in), the bash profile changes should be applied.
