Restarting .bashrc

Hey, I had had configured and working Docker. I tried to add some alias to .bashrc file. Unfortunatelly, after that I can’t connect with my container. I don’t know how to reset this file.
I used command to add alias just like in the Unix system echo ‘alias some=“something”’ >> .bashrc.
I cat this file and there is only this alias inside. I don’t know how to reset it.
