![]() ![]() Without sudo, users can’t elevate their permissions. The main purpose of the sudoers file is to control which users can run sudo. Then, type :wq, exactly as written, and press Enter to execute. Now that we’re done, we have to save and exit the document. It’s a handy way to accidentally nuke your system one day.Ĥ. You can also set the timeout to “-1,” which gives you an infinite grace period. If you prefer a different interval, enter that value in seconds instead. This will set your sudo timeout to zero seconds, so you’ll have sudo permissions for zero seconds after you execute the first command. Use the arrow keys and Enter key to create a new line at the bottom of the document. Press Shift + G to jump to the end of the document.ģ. This can be insecure, and some might prefer entering their password each time they use sudo.Ģ. Change the sudo timeoutīy default, entering your sudo password elevates your permissions until you close the shell or exit. It also holds some simple preferences, which we can adjust first to get a feel for how visudo works. The sudoers file’s main job is defining which users can use sudo for what. Returning users may want to check out a vim cheat sheet for a quick key command reference. vim relies on keyboard commands rather than mouse input, so it can be a little unfamiliar for modern-day users. If you’re not sure how to use vim, make sure the follow the instructions below carefully. The visudo command will open the sudoers file in vim by default. That only makes sense: we don’t want any old fool to edit sudoers. ![]() You need administrator access to run visudo. The visudo command opens the sudoers file properly and prohibits simultaneous edits. To edit sudoers, you’ll execute the visudo command in Terminal. A corrupted sudoers file means admin access is completely impossible until the file is fixed or replaced. Edit sudoers with TextEdit or similar and you can easily corrupt the sudoers file. Using a regular text editor is technically possible, but its an extremely bad idea. You must edit sudoers with the visudo command. But as long as single users have root-level permissions, personal machines like don’t require you to edit sudoers. ![]() System administrators, even small ones, might want power over who can run sudo and for what purpose. Your admin-level accounts are automatically added by macOS, and controlling other users is irrelevant. If your Mac is only a single-user device, it’s unlikely that you’ll have any particular reason to edit the sudoers file. You do not need to edit sudoers to add admin accounts, unless you want to limit an accounts superuser access. If you need to grant a standard non-admin user permission to run sudo, you will need to edit sudoers to manually add the user account. Standard, non-admin accounts created afterwards won’t have sudoers permission by default. This allows that account to run administrative tasks with the sudo command by default. When you first install macOS, the first and default user will be auto-added to the sudoers file. It controls how users can access the sudo command. Its a dangerous tool, and not every user should have access to it. Sudo allows users to execute commands that would otherwise be forbidden. It allows a user to run commands as root, the all-powerful superuser on Linux and macOS systems. If you’ve done anything with Terminal, you’ll recognize the sudo command. The sudoers file is a text file that lives at “/etc/sudoers.” It controls how sudo works on your machine. We can edit sudoers on macOS to administer a multi-user system more effectively. This file says which users can run sudo, and what they can do when they run it. ![]() Within your macOS system, there’s a file called “sudoers” which controls the deepest levels of your permissions system. ![]()
