How easy is to mess up a system with sudo!<\/p>\n

Rpm based distros help a little. I have to check in deb and apt offer something comparable<\/p>\n

If I run:<\/p>\n

sudo chown -R user:user \/\n<\/code><\/pre>\n
Can I revert it to what it was before I ran it?<\/p>\n
After sudo chown -R user:user \/<\/code>, it’s likely that the system is so badly hosed that you can’t<\/i> restore from a backup.<\/span> \u2013\u00a0Keith Thompson<\/a>Sep 22 ’12 at 23:59<\/span><\/a><\/span><\/div>\n<\/div>\n

If your distro is RPM based, you can restore ONLY files that installed by rpm packages.<\/p>\n
To restore all package permissions:<\/p>\n
rpm --setperms -a\n<\/code><\/pre>\n
To restore all package owner (user\/group):<\/p>\n
rpm --setugids -a\n<\/code><\/pre>\n
If -a doesn’t run, you can execute a bash loop:<\/p>\n
For permissions:<\/p>\n
for x in $(rpm -qa); do rpm --setperms $x; done\n<\/code><\/pre>\n
For owner:<\/p>\n
for x in $(rpm -qa); do rpm --setugids $x; done\n<\/code><\/pre>\n
