"Segmetation fault" after modifing .bashrc as a rootuser

[SomethingEat]

  I think i've broke my debian bad, wasn't following instruction closely... need to learn how to read again. I was trying to get color-coding to work in my terminal (different colors for directories, files, exec and such) and modified .bashrc files by adding something, i already forgot what to it, i think it was

source ~/.bashrc

everything else was commented out. Now I can't use sudo -s command, after punching in password it give me: Segmentation fault and kicks me back to regular user $. I've tried to open .bashrc with nano and vim, but both show nothing, nano says "Directory '.' is not writable" so i can't even show what i've done.  Is there any cure for that

What does the terminal say when you run " whoami " ?

 

Did you happen to add something like

 

if [ -f ~/.bashrc ]; then
	source ~/.bashrc
fi

To the top of the bashrc file?
