Undo a chmod command?

WingnutOne · 06-23-2008, 04:30 PM

I need to undo a recursive [chmod o-w] command that I ran on my /var/www directory. Is there any way to accomplish this?
I'm hoping that somewhere, the system actually kept track of which of the hundreds of files required changes and which didn't. Any help would be appreciated.

Thanks,
wn

PS: I did make a backup. It's corrupted.

nope, sorry. you'd need to chmod o+w whatever is relevant in turn.

There isn't really a way you can undo that. Recursive options to commands are very dangerous, as you just found out. :-/

However, it depends on what is in your directory. If it is all installed via RPMs, you might be able to use the rpm's --setguids and --setperms options. But since you said it was your www directory, I'm going to assume that alot of data was not from rpm.

Can you at least list out the contents of your backup? This might help you in terms of at least knowing what the original permissions are.

Yeah, I have a list of what they were before. But there's hundreds of them! Just didn't want to do them all manually if there was another option. (That's why I used the recursive in the first place.) Oh well. Ya don't always get what you want. :shrug:

Thanks anyway!
