Ubuntu

chmod root 777 recursive

Asked by Thierry GAONA - Axelor

Hello,

on french keyboard layout, the . and / caracters are side by side.

So that, I just made a "chmod -R 777 /" instead of a "chmod -R 777 .".

You guess the consequences...

I'm wondering two things now:
- How can I revert this miserable action?
- Even if an administrator has all responsibility using root user, would it be possible in some next version of Ubuntu having at least a message asking if we are sure to run such command which have the power to destroy the whole system...?

Thanks for the answer...

You could try:

sudo chmod -R 760 /

The whole point of sudo etc is that the user is given power, and with great power comes great responsibility. It will take a lot of effort to code this sort of thing in. A good rule of thumb is never use 777 ANYWHERE as it is hugely unsecure. It gives anyone at all ful access to your system so malicious code or java applets embedded in sites can affect the files with 7 as the last value (hence why 750 is good)

I suggest you research into Linux file permissions a little.

Can you help with this problem?
