'''
On Max OS X, when start a shell, it will read these files and execute commands in sequence:

~/.bash_profile
~/.bash_login
~/.profile

And it will read only one of them. So we will add environment variable in the same sequence.
Which means that
* add environment variables into ~/.bash_profile if it exists
* otherwise it will the add environment variables into ~/.bash_login if it exists
* otherwise it will the add environment variables into ~/.profile if it exists

Will create ~/.bash_profile when none of them exist, and add environment variables into it.
