bashrc

I am trying to setup a OpenStack box to have a look at OpenStack Object Storage (Swift). Looking through the web I found this link;

http://swift.openstack.org/development_saio.html#loopback-section

I followed the instructions line by line but stuck on step 7 in the "Getting the code and setting up test environment" section.

When I execute ~/.bashrc I get;

line 6: return: can only 'return' from a function or sourced script.

Below is the Line 6 extract from ~/.bashrc. My first reaction is to comment this line out, but I dont know what it does. Can anyone help?

#If not running interactively, dont't do anything
[ -z "$PS1" ] && return

I'm running Ubuntu 12.04 as a VM on Hyper-v if knowing that is useful.

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version.
