It seems you need to remove the edits you added to bashrc. Can you log in as root? IF so you can edit it from there. Otherwise, use a live CD or DVD such as Knoppix or Mint and you should be able to edit the file.
Hope that helps.

I cannot find it at the moment but I seem to remember this issue somewhere else, and it was an issue with a 64 bit OS and java not being compatible. It might be worth checking when you get it fixed

Hi all,

Thanks for your suggestions. I'll try what you have suggested and give a feedback.

if you still can't log in as root, try this (if you don't have a LiveCD handy, which would work just fine, of course), as it's a little quicker:

Reboot, and at the grub/boot prompt, interrupt the boot process by pressing the [Tab] key, then type [A] to modify the kernel args, then append this to the end of your kernel args line:

 init=/bin/sh

Then press [Enter]. It should boot up and dump you right to a bash prompt. First you'll need to mount your root filesystem read-write:

mount -o remount,rw /

Then you can edit the bashrc as suggested. Then reboot.

hi,

I was able to boot from a live CD and access the /etc/bashrc but the content in the file is different than we get by typing gedit ~/.bashrc command hence I was not able to track my changes

[atreyu]

yeah, those are two different files.

The /etc/bashrc is a system-wide BASH file that gets read by anyone logging that uses bash as their shell.

The tilde in ~/.bashrc refers to your home dir, or the equivalent of the $HOME variable, which gets set when you log in. This bashrc file only gets read by this user, so usually has user-specific bash settings.

So if you were root, then the file is probably /root/.bashrc. but maybe you already know this? couldn't tell from your post...

These are just paths and should not stop you from logging in.
I think the bigger issue is what did he also include/remove from the original file?

The question is which bashrc file did you modify?
The one in /etc or the one in /home/user?

And the most important question did you make a backup before changing the file?

I entered the ~/.bashrc command after changing to root user prompt from my default user login. So it should be root. The thing is when I enter the username and password for my normal account the password get authenticated and of in a flash again it directs to the login page. Even when I try to log as root it doesn't allow to login.

thanks
