Bashrc and profile in common operating systems

Let's first look at bashrc and profile in common Linux systems:

In CentOs:

/etc/profile/etc/bashrc~/.bashrc~/.bash_profile

In Ubuntu, Debian:

The requested URL/etc/profile/etc/bash.bashrc~/.bashrc~/.profileShell was not found on this server.

Before you can understand these files, you need to understand the login and interactive modes of Shell.

login shell and no-login shell

There are many kinds of shells in Linux system, such as bash, sh, zsh, etc. If you want to see what shell a user is using, you can use the finger [username] command to view it. We're only talking about shell bash here, because if it's sh or any other shell, it obviously won't run bashrc.

"login shell" stands for user login, such as using "su -" command, or using ssh to connect to a server, will use the user default shell to start login shell mode, the shell in this mode will automatically execute/etc/profile and ~/.profile files, but will not execute any bashrc files, so generally in/etc/profile or ~/.profile we will manually go to the source bashrc file.

In the case of no-login shell, we directly enter bash or bash -c "CMD" in the terminal to start the shell. In this mode, no profile file will be automatically run.

Thank you for reading, the above is the "bashrc and profile difference in Linux" content, after learning this article, I believe we have a deeper understanding of the difference between bashrc and profile in Linux, the specific use of the situation also needs to be verified by practice.
