How to run command as administrator?

Question

In terminal, I find this and it does not respond well to my orders, what should I do?

To run a command as administrator (user "root"),
use "sudo <command>".
See "man sudo_root" for details.

This message is found in the beginning of terminal.

if any command needs to be executed as root, use sudo word before the command. like sudo mv file1 file2 — Anwar, Sep 08 '16 at 15:24

Just use sudo <command>, where command is the order, or instruction you want to run as superuser. If you get an error like:

user is not in the sudoers file

You must edit the /etc/sudoers file. To do so, type

su

Enter the root password

Then, you can use nano or vi to edit the file, for example:

nano /etc/sudoers

Look for a line like this:

root    ALL=(ALL)       ALL

And add a new line bellow this, like:

myUser    ALL=(ALL)     ALL

Now, reboot your computer, and then try to use sudo.

Regards.
