alias rm="rm -i" won't work.
Neither will creating a file named '-i'

Example;

touch /tmp/test

rm -i -f /tmp/test

It WON'T prompt. -f take priority over -i.

Hm. Maybe you would have to be able to access the filesystem from a live-CD or put the disk temporarily in another machine to fix that...? So that it was not your root system. Then I guess you should be able to issue a `chmod a+r whatever' or `chmod -R a+r whatever' on the relevant directory(ies) as root, unless the filesystem was encrypted or something...

But then maybe there are some magic you could do from the kernel boot command prompt of your bootloader (thinking "grub") that would help, but I'm not skilled enough to know this.
Anyways, I always stop to read twice and think a bit before issuing a possible really dangerous command as superuser...

2008-12-03T05:57:00.000+08:00

Nobody said this one?

yes > /dev/sda

and the IQ test for new linux admins;

touch -- /-rf

and I'd also like to point out that adding alises for 'rm -i' are completely useless... 'rm -if' or 'rm -fi' won't prompt.. the -f takes precedence. If you're prone to silly typos though, alias rm='mv -t ~/.Trash/' might be a good idea.

Lol, the forkbomb looks really out of place.

Biggest reason I don't use linux is after a couple of boots (usually within the first week), it fails to load for some reason.

Funny. I've had Linux boxes running, literally, for years. But then, I'm a Unix admin.

The nice thing about Linux is that it isn't maintained by control freaks or people who are driven by profit motive to be constantly rendering their product obsolete and in need of another upgrade. It's maintained by people who like to see it working with as many applications and for as many people as possible.

To the guy with the Linux working for a week. I've had a similar, if not same, problem. Perhaps you're hard disk is not checked for bad blocks. Use the "badblocks" program to scan your devices for these bad blocks and then add the -B option along with your mke2fs, or whichever mkfs you're using. Use man pages for help. This will prevent Linux from messing up again or any of those weird I/O errors.
