[SOLVED] Accidentally changed /usr to 755, how to fix?

r1pp3rj4ck · 2012-06-13 09:21:26

I was a bit too tired and when pacman was giving me warnings for some files about being 775 in filesystem and 755 in package, so I thought it would be a good idea to chmod -R 755 /usr. I was wrong. But now I'd like to fix it. I changed the whole stuff to +s, but the GTK+ stuff are not working now. I changed everything back to -s and give +s only to sudo which is now working fine, but the startx still won't start my Xfce. I guess there are more problems. I've been Googled around for some time now, but I didn't find anything useful and it's a bit hard to search with elinks. Could you post how to fix startx/startxfce4/GTK+ apps and maybe which apps need setuid by default? (I know sudo does, it's already done).

Thanks for your help,

Easiest way is to reinstall all packages.

Won't pacman just complain about permissions being different than the package suggests?

Thanks Allan and Awebb
This is what I did:

# chmod -R 0755 /usr
# chmod -R -s /usr
# pacman -S `pacman -Q | awk '{FS=" "; print $1}'`

(actually I wrote it in a file first so I could remove the packages from the file which were installed from AUR - I don't know what the inverse for pacman -Qm is, I haven't found it in the manpage of Pacman).

Oh and I also managed to re-install the AUR stuff too (only those ones which I haven't deleted yet):

# for pkg in `pacman -Qm | awk '{FS=" "; print $1}'`; do if [ -d $pkg ]; then pacman -U $pkg/*.xz; fi; done;

Sometimes I wish we had a counterpart to -Qm, a -Q!m to filter packages NOT manually installed.

diff <(pacman -Q) <(pacman -Qm) | grep "<" | awk '{print $2}'

Not pretty, but it works.

Awebb, me too Pres, I actually like it, it's creative I guess I'll write a blog post about this, with the extension suggested by Pres, referencing all you guys. Thanks for the help once more

Yes, that's the way we roll. That's also why I have not bothered asking for this feature in a bug yet, it's not hard to solve.

I use a slightly different command

(pacman -Q ; pacman -Qm) | sort | uniq -u
#Without versioninfo
(pacman -Qq ; pacman -Qqm) | sort | uniq -u

Nice. Usually there are several solutions to problems like these. Your's looks like a neater solution than mine.
