    Have problems with my Mac and I want to repair the permissions and disk, when booting from a bootable backup. But it's been removed for Disk Utility in El Capitan. I've read you have to do it through Terminal, but don't know the exact line I have to enter when I've booted from a backup and want to do it on my main harddrive.

    El Cap automatically repairs disk permissions.

    If you're having a problem with your Mac, it's highly unlikely that would fix the issue anyway. Please can you describe the symptoms & provide the model/year of your Mac? From here we'll try a few other diagnostic tools.

    Eh...
    El Cap doesn't technically "automatically repair disk permissions", but does not allow the permissions to be modified, particularly for the built-in system apps. It's part of the SIP security feature.

    You CAN repair permissions in El Cap - although, as keysofanxiety said, it's unlikely to fix your issue. But you can try it out...
    Here's a web page for that.
    The default command will "repair permissions" on the default boot drive. If you want to repair permissions on another drive, then you have to delete the / , and specify the volume that you wish to "repair permissions"
