True, SGID would affect the group it runs as, while SUID affects the user.

You could set up things so that a group has permissions to do what you want, instead of the root user. But then this also depends on the usecase, I’m not sure if having root group permissions would be enough in all cases.

What do you mean by “not require sudo privileges”?

Do you mean not require root permissions? that depends on what are you trying to do. You’ll need to make changes in your system to allow normal users to have permissions for it, and in many cases that’s not possible (or very safe).

If what you mean is that you don’t want to need to type"sudo" every time, but still be able to have the commands run with root permissions, then there’s multiple ways to do this:

• Add an alias such as alias command='sudo command'. If you don’t want to type the password, you can change the sudores file so that your user doesn’t need to enter a password when running sudo for that command (someone else in the comments already explained how to do that, using an entry with NOPASSWD: /usr/bin/command in the sudoers config).

• alternatively: set the SUID bit of the executable you want to run, so that every time the file is executed (by anyone) it will always execute as the user who owns the file (so if the owner is root, the file will always be executed as root)… this is not something I’d recommend though, since it can lead to security vulnerabilities.
