The article is rich in content and analyzed and described from a professional point of view. I hope you can get something after reading this article.

Log in to the system to read:

When logging in to the system to get a shell process, there are three steps to read the environment profile:

1. First read the global environment variable profile / etc/profile, and then read the additional set documents according to its contents, such as / etc/profile.d and / etc/inputrc

two。 Then, according to different user accounts, go to their home directory to read ~ / .profile. If this cannot read ~ / .bash_login, it will read ~ / .profile only if it cannot be read. The settings of these three documents are basically the same, and there is a priority for reading.

3. Then read ~ / .bashrc according to the user's account number

/ etc/* and ~ /. * difference:

/ etc/profile,/etc/bashrc is the system global environment variable setting

~ / .profile, ~ / .bashrc is the setting of private environment variables in the user's home directory.

The difference between ~ / .profile and ~ / .bashrc:

All have the function of personalized customization.

~ / .profile can set the user-specific path, environment variables, etc., which is executed only once when logging in.

~ / .bashrc is also a user-specific configuration document. You can set paths and command aliases, and use it once for every execution of shell script.

The above is the difference between setting / etc/profile, / etc/bashrc, ~ / .profile and ~ / .bashrc for the Linux environment variables shared by the editor.
