Problem Help!

[Dixit, Viraj]

Hi,

In my haste I edited my rc.conf file and knowing well that if I make a mistake I will get hung the system at that point. I need an expert help to get me out of this situation. I spent days building the system, I don't want to do the whole thing again. I must have forgot a quote in my rc.conf file and now when the system got rebooted it's asking for pathaname for the shell. I am not sure of the next step. Help!!
Thanks
