Mac OS Environment variables

We generally use the user profile below, use CD ~/to see Bash_profile, configure the environment variables you need to configure inside, and then through the VI command to edit the file

(1)/etc/profile

A global (public) configuration that reads the file when logged on, regardless of the user.

(2)/ECT/BASHRC

Ubuntu does not have this file, and it corresponds to the/ECT/BASH.BASHRC

It is also a global (public)

When bash executes, this file is read in any way.

(3) ~/.profile

If bash is executed in login mode, read ~/.bash_profile, if it does not exist, read ~/.bash_login, if the first two do not exist, read ~/.profile.

In addition, when graphical mode is logged in, this file will be read even if there are ~/.bash_profile and ~/.bash_login.

(4) ~/.bash_login
