How to launch clean bash session
 

how to launch a non-login bash session that doesn't inherit its parents environmental variables, and doesn't source /etc/bashrc?

Maybe using something like this:
see man env and man bash for details about the mentioned options. BTW we could suggest a better solution if you provide more details about what you're trying to accomplish. Hope this helps.

Thanks
 

Thank you! I just needed a clean environment to test a program that sets up the environment. I couldn't change the rc files under /etc since I am not the admin.
