How do I add a standard user into sudoers' file using `echo`?

Question

I am using Ubuntu 12.04 and I was doing through a terminal tutorial. There was explained about echo command and he mentioned something about adding your name to the sudoers file using echo >>. I am just wondering what it was? Can anyone tell me how to do it?

I went to /bin and typed ls and the first file was bash so i think i should type echo jatin >> bash but i am not sure so just asking? :| — Jatttt, Feb 22 '14 at 20:13
1) do not _ever_ try to `echo` something `>> /bin/bash` that will break your shell. 2) Do not _ever_ use `echo` to modify `sudoers`, use `visudo` instead. If you found a guide telling you to use `echo` for this, change guides and ignore anything else it recommends. — terdon, Mar 19 '14 at 00:40

First login as root using the following command:

sudo -i

Then type:

echo "username ALL=(ALL) ALL" >> /etc/sudoers

Change username with your user name.

It will add the username to sudoers file. But doing this may lock out you from sudo.

Only users having root privileged can do it,standard users can't. – g_p Feb 22 '14 at 20:23

Downvoted because the way you have suggested to use sudo simply won't work in this context (it is the redirect `>>` that needs elevated permissions) – steeldriver Feb 22 '14 at 20:30
@steeldriver Now it will work – Radu Rădeanu Feb 22 '14 at 20:38
Although that will work, the "problem" is that sudo will not allow redirect directly. You can use tee or sudo bash -c "echo >> ..." – Panther Feb 22 '14 at 22:15
