how to source with sudo -u

Question

Redhat Linux using Bash

1. I login in as myself
2. sudo to another user

sudo -u bash

I want to call a bash_profile when I do this. When I run this, I get the following error

bash: /home/myuser/.bashrc: Permission denied

Myuser: the username that I log in with.

Answer 1

sudo -i -u username 

should trigger the login shell for that user, as suggested above, and pick up all their .whatever preferences.

Alternatively, I'm more in the habit of doing this:

sudo su - username
