The question, and the answer content:
Try using a live distro to edit or remove your /root/.bashrc.
The answer is correct, but it's far from being a good answer. The question already knows it's a broken
/root/.bashrc file so the answer might as well just say:
The OP figured that out and restored the file from
/etc/skel/ in the end. They should have posted that as the answer but I hope you can see the difficulty in deciding what we do with answers like that and why it came down on the side of deletion this time.
In an ideal world somebody would have replaced the answer with a better one (or closed it against one of the other versions of that question where the file is restored) but given the OP had their solution before the answer was deleted, it might not have seemed necessary.
I also know that I have a lot more information than you're presented with when given it to review. I think this is one of those times where the audit isn't fair.
Thankfully it's only an audit.
