Hey Dan,
RPM has a fairly groovey feature which will let you reset the
permissions to match their stored values in the rpm database. For
starters something like...
rpm -q -a | xargs rpm --setperms
... will set most of your box to rights. Except there are quite a few
'unowned' files in /etc so.. Assuming I didn't misunderstand your problem
I think this should work out...
M.
#!/usr/bin/perl
use strict;
use File::Basename;
use IO::File;
use vars qw / $backdir $backfile $targdir $targfile /;
use vars qw / $mode $f /;
$backdir = "/mnt/backups/etc";
$targdir = "/etc";
$f = new IO::File;
open ($f, "find $targdir|") || die "Find failed: $targdir: $!\n";
while (<$f>) {
chomp($targfile = $_);
$backfile = $targfile;
$backfile =~ s/^$targdir//;
$backfile = $backdir . "/" . $backfile;
$mode = (stat($backfile))[2] ||\
print STDERR "Stat failed: $backfile: $!\n";
printf "$backfile: %04o\n", $mode & 07777;
chmod $mode, $backfile;
}
exit(0);
