Help restoring file permissions from a Dump

bminish · 12-11-2004, 06:44 PM

I have messed up my file permissions
sudo chmod -R 777 / instead of sudo chmod -R 777 /mnt/some_dir

I have daily dump files and I would like to restore all the file permissions from these dumps, preferably without actually restoring the dumped files since restorign the files will overwrite all the things that I did today

any help apprecated. I am running fedora core 3

regards
Brendan

Hi, and welcome to LQ!

Can I introduce you to one of LQ's most excellent
features? It's the "search" button.

There's a list of post with a similar topic.

And this is probably what you wanted ... part
of the search results.

Cheers,

Thanks Tink but the search results only deal with restoring permissions from the rpm database, whilst this is useful this does not actually help me much
I have a full and fairy up to date backup of my entire file system. I can if there are no other options restore the entire dump but would prefer to just restore the permissions from the dump file without actually restoring the files.

Sorry - my bad :}

/me makes the excuse that he had high fever and didn't think straight...

What you could do is extract the information you need
using tar -tvzf (or tvjf if bzip compressed) and feed that
back to chmod ... a bit of scripting to translate
-rw-r--r-- (and the likes) into something chmod can under-
stand should be possible within a reasonable abount of
time...
tar -tvzf dump.tgz | awk '{print $1" "$6}'
being the base you want to use...

Cheers,
Tink
