my bash file is deleted , trying to restore from kernel arguments
 

hi,
i have deleted my bash file
and thus the system is not letting me to bash shell
now i have a kernel panic situation
i want to log in using ksh shell passing arguments from kernel
lets begin..

Please tell us which distro & version you have, and give more details.
Which 'bash' file?

1. /bin/bash - the actual shell itself
2. .bashrc
3. .bash_profile
4. other

yeah you got it right
its the /bin/bash file
i am using RHEL5

I'd use the installation DVD in rescue mode ie at the first text prompt type

linux rescue


then it will run from the DVD & mount your HDD as another disk. You can fix your login to use /bin/ksh or whatever so you can at least get in.
You should then be able to use yum to re-install bash.

boot into "linux rescue" mode from the installation disc

Then you can do 1 of 2 things...

Reinstall bash

Copy bash from the rescue mode

-C

the point is i don't want to use the dvd , or linux rescue mode... i want to fx it by passing arguments from the kernel to get into the computer using ksh shell

So this is homework. If I were in your shoes I would use the simplest, most reliable way to recover from such a disaster (e.g. copy bash from a rescue disk to the affected installation). But you don't want to do that. Ergo, homework.

Be truthful.

Do you mean passing options to the kernel using grub?

-C

correct
i think something like
init=/bin/ksh should work

It might...try it out and let us know if it worked.

-C
