Little accident with chmod

svu · 09-25-2011, 05:36 PM

Hi,

I was trying to get my canon mp540 to work in Slackware 13.37... (which it does now btw, so yay)

While i was changing some permissions in /usr/lib/cups i somehow managed cd myself to /usr/lib and there i executed the beautiful command : chmod 777 *

So...

There are some 137 files with their permissions screwed up...
Most stuff seems to work so that is not a real problem for now but I was wondering what are the consequences ? Do I need to fix this ? And ... how should I go about fixing it ?

Thanks

I would think that

Code:

cd /usr/lib
chmod 755 *

would do it.

Hello,

Most likely, you will be safe by running the following within that directory:

Code:

chmod 644 *

After that, chmod +x known files you know need to be executed, which I think there shouldn't be any.

Cheers,

Josh

thanks,

I have no idea if the permissions were indeed 755...

Is it some kind of well known fact that the default permissions on those files is normally 755 ?

Is there any way to be sure that those were the correct permissions on all those files in /usr/lib ?

Hey,

I'll try something like that...

Would it be ill advised if I keep the permissions set to 777 ?

Um, on my -current system it looks like directories are 755 (drwxr-xr-x) but at least some files are 644 (rw-r--r--)

Thanks for the overview!

Most of the .la and .so files are 755 with the exception of a few.

I have attached what I have.

Hi,

this is a somewhat odd response in an unrelated thread - but unfortunately
you don't have private messages on the board enabled: when responding
to the e-Mail you sent me earlier today my mail got bounced by hotmail
with a 550 Requested action not taken: mailbox unavailable (state 14).

Can you please contact Jeremy directly with your initial inquiry?

Regards,
Tink

Thanks a lot for noticing.
I changed my LQ settings and emailaddress (was still using an old one that has been disabled).
