Bash Invocation of non-login shells: Which configuration Files?

teancum144

According to the LPIC-1/CompTIA Linux+ Certification All-in-One Exam Guide:

If you’re using a non-login shell, things are pretty straightforward. The bash shell simply runs /etc/bashrc for system-wide functions and aliases, and then it runs ∼/.bashrc from the user’s home directory for user-specific customizations.

However, according to the following: https://www.gnu.org/software/bash/manual/html_node/Bash-Startup-Files.html#Bash-Startup-Files

When an interactive shell that is not a login shell is started, Bash reads and executes commands from ~/.bashrc, if that file exists.

The above is in conflict. Does Bash execution the /etc/bashrc file prior to the ∼/.bashrc or not? What script could I look at to verify this?

Pretty easy to confirm... create an alias in one or the other and try to use it.

I'm a little unclear? Would you mind providing a little more detail?

Here's another source:

An interactive nonlogin shell executes commands in the ~/. bashrc file. The default ~/. bashrc file calls /etc/bashrc.

Create an alias in one of the bashrc files and try to use it under both conditions. One will fail and you will know which one works.
