file premission problem. (URGENT)

cyberia_2ooo · 04-17-2003, 08:14 AM

well, I have tried to install a driver for my ATI graphics card.
the official RPM (which i converted to TGZ) didn't want to get installed, so i got an unofficial one.
converted it, installed it, tried to run, didn't run, uninstalled it.
(all of that, i have done under roor)
Then, I restarted my machine, logged in as a regular user, and couldn't run nothing.
after an investigation i figured out that all the files an folders premmisions were messed up.

does anyone have any idea what to do?
maybe someone here has a script, or can make script, that will change back to defaule file premissions?

Exactly which files are you talking about? And what are their permissions at the moment.

cheers

that's it, it's one or two files

i noticed that the directory /usr's premissions were drwx------
and many subfolders and files of it were with the same premission.

I noticed the problems when i couldn't run anything from regular users....
after i changed some permissions so i could start x (which was one of the programs i couldn't run) it gave an error because it couldn't read a file, after changing the file's premissions, it gave me a new error about another file....

now, i want to change back to default file permissions.

If you are in a situation where all the files and directories in the current directory and below are 700 when you want them to be 755 and 600 where you want them to be 644 you can use a little perl script like this...

Code:

#!/usr/bin/perl -w
use File::Find;

@ARGV = ('.') unless @ARGV;

find(\&process_file, @ARGV);

sub process_file {

   if ( -d ) {
     chmod 0755, "$_";
     print("chmod'ed $_/ to 755\n");
     return;
   }

   if ( -x ) {
     chmod 0755, "$_";
     print("chmod'ed $_ to 755\n");
   }
   else {
     chmod 0644, "$_" ;
     print("chmod'ed $_ to 644\n");
   }
}

You'll need to save that to a file, chmod the file to 700 then run

Code:

theFileNameYouChose /someDir

If you don't give it a directory then you'll end up chmod'ing the current dir.

thanx alot
but' it's not exactly what i wanted....
see, there are files which are not supposed to be accessible for regular users in the folders like usr or var

but, there are files there which are accissble and even writeble by all users...

I don't wanna have any security holes

That script will only be suitable if you want root with read/write and everyone else with read. If you need anything more complex then I recon' you'll need to do it by hand.

good luck!
