Make sudo command not need sudo?

I would like to set a specific command to not require sudo privileges, is there a way to accomplish this? I know you can add commands to the sudoer file to allow certain commands to be used by non root accounts, so maybe there is something similar for adding commands to allow regular users to use?

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.
You can change the permission of the files that are used to execute, and you can change permission of the files that are being touched.
But probably the easiest solution would be to create an alias to the command that uses sudo transparent to the user, while also adding the permission to sudo without password in the sudoers file.
You can do that in the sudoers file. I don't know how exactly, but that won't be too hard to search for.
- Thank you
This does seem to be exactly what i am looking for. I implemented this and tested it and the command still isn't working yet but i will keep troubleshooting, its probably a silly quirk on my end. Thank you very much!
