Why is `source /home/vagrant/.bashrc` not working in a Vagrant shell provisioning script?

Question

I'm having problems with a shell provisioning script used by Vagrant, as it's not executing source /home/vagrant/.bashrc. I've reduced the problem down to this...

Within my VM I have a file at /home/vagrant/testfile that contains this:

echo "In testfile"

And at the end of /home/vagrant/.bashrc I have this:

echo "In .bashrc"

Both files are owned by the vagrant user.

In one of my Vagrant provisioning shell scripts I have this:

echo "Hello"
source /home/vagrant/testfile
source /home/vagrant/.bashrc
echo "Goodbye"

Running vagrant provision gives this:

Hello
In testfile
Goodbye

When I do vagrant ssh then /home/vagrant/.bashrc is run as usual, and I automatically see:

In .bashrc

So why does doing source /home/vagrant/.bashrc have no effect from within my provisioning script?

You need to remove the “exit if not running interactively” bit (e.g. [ -z "$PS1" ] && return) from the top of your .bashrc.
