This evening I made a big mistake while changing permissions, and can no longer login to my computer. With my Home folder open, I was trying to change the permissions on several music folders - I had a lot of folders, so I decided to hit Ctrl-A to change it automatically on all my music folders, and also hit the 'apply to subfolders and files' button.
The Ctrl-A selected ALL of the folders on the machine, but because I have enough music folders to fill more than a screen, I didn't realize it until after the fact. Suddenly, my computer couldn't recognize any file on the computer, couldn't tell what they were, couldn't even recognize the folders as folders, so I couldn't even open them. I couldn't change the permissions back, because the computer couldn't figure out what the files were in the first place.
In a panic I restarted, and now I can't even log on. I can't log on in failsafe mode, except a failsafe terminal, which I don't know how to use effectively enough to help me, or really at all for that matter. When I try to log on I get a message that 644 permissions are gone (or something along those lines) and then "Your last login attempt lasted less than 10 seconds. If this is a problem, try booting in a failsafe mode."
If anyone can give me some tips, I'd greatly appreciate it - I'm in college and NOT deleting all the stuff that I hadn't quite gotten around to backing up in the last 60 days or so would be wonderful, and so would having a computer again... I'm currently running Celena 3.1, and right now off the boot CD - I can't seem to even find the screwed up files through the CD, so I don't know how to fix them at all.
For the record, I'm relatively new with Linux, so I know the basics but that's about it.
Thanks for your help!!
