i have figured out that i have changed my disk permissions, and my computer won't start up.

when i boot from the cd, i can get a termial. but i have bash-3.2#, and i can't figure out how to get it so i can use a normal command. the preferences are greyed out. any help would be appreciated

If you're booting from the installation discs, you can select to launch Disk Utility from the menubar when you've reached the Welcome installation window. Once Disk Utility launches, then you can perform a Repair Permissions on your hard drive and see if that resolves your problem (since you did mention that it was a change in permissions that caused the problem).

If you're daring, you can also do this by booting into Single User Mode (hold down Command-S when you hear the startup chime). This mode is all text-based and you use the command line. Once at the shell prompt, you can follow these directions which I took from this thread post on macosxhints.com:

After the Command-S startup, type the following on the command prompts, allowing time for each to do its thing:

/sbin/fsck -y <hit Return key>
/sbin/mount -uw / <hit Return key>
/sbin/autodiskmount -va <hit Return key>
/usr/sbin/diskutil repairPermissions / <hit Return key>

And, when one is sure it's all done, type:

reboot <hit Return key>
