Corrupted /etc/passwd

Hi

I have installed solaris 9 on my Intel Box at home. Once I have changed the defaukt sheel for root as /sbin/bash instead of /sbin/sh. After that when I have restarted the solaris, it will not allow me to login as it showes the error as "Invaild Shell". Now can you suggest me how I can resolve this issue without reinstalling the os.

Thanks in advance

You should boot your box using the installation CD and then mount your disk to /a, i.e:

Code:

mount /dev/dsk/c0d0s0 /a

Then change dir to /a/etc and edit your /etc/passwd replacing /sbin/bash with /usr/bin/bash.

You have to put

Code:

b -s

when prompted for the type of installation you want to perform. You can also do the same while booting from the boot disk when prompted to select (b)oot or (i)nterpreter.

the problem was that you changed it incorrectly. The path to the bash shell is /bin/bash. You will have to boot from the cd into single user mode, mount the root file system into /a or /mnt in the cd and edit /etc/passwd to put back the correct shell. Also, don't forget to set your editor variable and terminal variable.

Once you do that, just reboot and you are done.
