I messed up bigtime with the bashrc file. I was installing Gurobi and I had to set path variables in the bashrc file. So, I replaced all the text in bashrc with the path variables and saved the bashrc file. And I also made sure, if anything bad happens, I have a backup of this file. The original unmodified backup file is in the Downloads folder.
Now when I restarted the system, I was not able to login despite giving the proper password. Hence, I'd like to ask you for some help. What kind of fixes are possible given the fact that I still have the bashrc file in the Downloads directory
