Make sudo command not need sudo? (self.linux4noobs)

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?

Well my other comement saying this is exactly what i need did not get posted as a reply to your comment, my mistake. I followed rhe example for "/usr/bin/wg/" intending to be able to use

wg show

but it still requires sudo. I tried rebooting and nothing changed, any ideas? I did

type -a wg

to get the command location for the sudoer file.

Well my other comement saying this is exactly what i need did not get posted as a reply to your comment, my mistake.

What the line I listed will do will let a specific user have permission to use sudo without a password to run wg as root without a password. So they (and not other users) can type:

$ sudo wg

And the command will run as the root user, without them being prompted to enter a password.

It doesn't mean that when that user runs:

$ wg

In their shell, what will actually run is:

$ sudo wg

If you also want to avoid typing the extra characters, you can set up an alias in your shell.

I don't know what shell you're using, but most Linux systems use bash as a default:

 $ ps
    PID TTY          TIME CMD
1413558 pts/3    00:00:00 bash
1413640 pts/3    00:00:00 ps
$

If you're using bash, you can tell your current bash shell invocation to do that with the alias command:

$ wg
Unable to access interface wg0: Operation not permitted
$ alias wg='sudo wg'
$ wg
interface: wg0...

If you want that command run in every bash shell you invoke, you can do so by editing ~/.bashrc and adding the line:

alias wg='sudo wg'

Awesome now I understand what you and the other commenter were talking about with aliasing. Well this works perfect without the alias, many thanks
