So we will add environment variable in the same sequence. Which means that * add environment variable into ~/.bash_profile when exists * add environment variable into ~/.bash_login when exits and ~/.bash_profile not exits * add environment variable into ~/.profile when exits and ~/.bash_profile & ~/.bash_login not exist Will create ~/.bash_profile when none of them exist, and add environment variable into it.
