Question

What is the script calling order on bash login?​

Answer 1

Answer:

$HOME/.bash_profile

I would highly recommend against using /etc/profile.d/yourscript.sh if it produces output. When you use a non-interactive session, you will receive a $TERM is not set message. This is noticeable when using the ssh protocol, like scp. Usually not a big deal, however, Veeam doesn't like it and will throw a warning. I know Veeam is not the topic here, but it's worth mentioning that not all applications will gracefully ignore the $TERM is not set warning.

In short, if the script generates output, place it in the locations specified on the first line. However, if you're modifying the environment and your script doesn't generate output, then use the latter.
