Note on Login vs Non-login Shells

There is much confusion about how .bashrc and .bash_profile are read. This article explains the issue.

To summarize: A login shell means that you got the shell after authenticating to the system, usually by giving your user name and password. Files read:

~/.bash_profile

A non-login shell means that you did not have to authenticate to the system. For instance, when you open a terminal using an icon, or a menu item, that is a non-login shell. Files read:

~/.bashrc

For this reason, to unify the environments between both login and non-login shells, the .bashrc file should source the .bash_profile file.
