When Bash is invoked as an interactive login shell, or as a non-interactive shell with the--loginoption, it first reads and executes commands from the file/etc/profile, if that file exists. After reading that file, it looks for~/.bash_profile,~/.bash_login, and~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The--noprofileoption may be used when the shell is started to inhibit this behavior.

100% agree, /etc/profile is the right answer!

No way, it's not /etc/profile.alias!

I’m pretty certain it’s /etc/profile, but I should double-check my notes just in case.

I remember practicing a similar question, and I think it was about the login shell configuration files.

I think the first file executed is /etc/profile, but I'm not completely sure.

I’m a bit confused; I thought it might be -/.alias, but that doesn’t sound right now.

I've got a strategy for this - I'll start by listing out the possible configurations and then narrow it down based on the options provided.

This question seems straightforward, but I want to make sure I understand the requirements correctly before answering.

Okay, I've got this. The principles of "exhaustive testing is not possible" and "where many errors exist, more errors are usually hidden" are definitely true. I'll select those two options.
