Restore OS X El Capitan system permissions to default

Hello, I would like to ask, if there's an option to restore system permissions to default? I've accidentally run command sudo chmod -R 777 / and didn't notice the root path, so after that my system was broken and I was unable to boot. I've reinstalled the OS from recovery mode, all my data and installed application remained unchanged, but the system permissions are still broken (777), so it throws an error almost after every command in terminal. What's the solution of my problem? Thanks for an answer!
