How to load Bash with .bash_profile from different folder

Question

I have a shell script project where I want to load the .*rc from the project folder.

In zsh I can achieve this by ZDOTDIR=$PWD zsh which will load the .zshrc from the current folder.

How can I do the same in Bash?

Answer 1

Launch bash with the --rcfile option

bash --rcfile ./project/bashrc
