Note on interpolation

Invoked as an interactive login shell, or with `--login'

# Interactive means you can enter commands. The shell is not running because 
#+ a script has been activated. A login shell means that you got the shell after
#+ authenticating to the system, usually by giving your user name and password.

Files read:

• /etc/profile
• ~/.bash_profile, ~/.bash_login or ~/.profile: 1st existing readable file is read
• ~/.bash_logout upon logout.

Invoked as an interactive non-login shell

#  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

This file is usually referred to in ~/.bash_profile: if [ -f ~/.bashrc ]; then . ~/.bashrc; fi
