Changing File Attributes

terdbird · 04-23-2005, 02:45 AM

How do I change file attributes? I mistyped my root password, so I had to do the linux init=/bin/bash, and now i cannot re-write the /etc/passwd because it is read-only. How can I get around it?

Edit lilo or grub and take out the ro. Then you can boot it up and take out the cryptic string in /etc/shadow.

Try: /sbin/mount -w -v -n -o remount /
That should remount it with read-write attribute.

Oh yeah forgot lilo has to be edited and then rewritten to the mbr, which you can't do of course. With grub you can though, just hit c at boot and take out the ro. I'm not quite sure how that would work with lilo since I use grub.

Neo, you can give LILO parameters when you're booting (without having to rewrite it), I think by giving this parameters:

Code:

init=/bin/bash read-write

will mount the filesystem as read-write.
Grub is also good, somehow different (it's more dynamic), I think it's just a matter of taste.
