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 variable sinto ~/.profile if it exists Will create ~/.bash_profile when none of them exist, and add environment variable into it.
