Answer 1

I happen to be curious about these files and did some experiment myself. It turns out to be a little different than what is in the documents.

I know the differences between interactive and non-interactive or login and non-login.

I tried on two computers, my macbook pro with OS 10.9 and a server with ubuntu server 13.10. I add the following command into the /etc/profile:

echo "Loading /etc/profile"

And similar commands into /etc/bash.bashrc, /etc/bashrc, /etc/bash.bashrc, ~/.profile, ~/.bash_profile, ~/.bashrc, ~/.bash_login and make sure that these files do not source each other inside themselves.

(OS 10.9, GNU bash, version 3.2.51(1)-release (x86_64-apple-darwin13)) On the mac, with interactive login bash, I have:

Loading /etc/profile
Loading ~/.bash_profile

Which means that the files loaded directly are only /etc/profile and ~/.bash_profile.

with interactive non-login bash, I have:

Loading ~/.bashrc

which means that the file loaded directly is ~/.bashrc.

(ubuntu server 13.10 GNU bash, version 4.2.45(1)-release (x86_64-pc-linux-gnu)) On the ubuntu, with interactive login bash, I have:

Loading /etc/profile
Loading ~/.bash_profile

Which means that the files loaded directly are only /etc/profile and ~/.bash_profile.

with interactive non-login bash, I have:

Loading /etc/bash.bashrc
Loading ~/.bashrc

which means that the files loaded directly are /etc/bash.bashrc and ~/.bashrc.

I do not know why~
