I want nopasswd thing for my jenkins user. For that, I have to edit the /etc/sudoers file,

But 

luvpreet@DHARI-Inspiron-3542:/$ sudo vi /etc/sudoers

This gives me that this file is readonly and so, I cannot edit this file.

I change to root,

luvpreet@DHARI-Inspiron-3542:/$ sudo su

And I am getting something like this, 

\[\e]0;\u@\h: \w\a\]${debian_chroot:+($debian_chroot)}\u@\h:\w\$

and even now I cannot edit the file. It still says this is readonly.

What is wrong ?

How do I solve this issue ?

    got it, I have to use the sudo visudo command. But when I log in as root, why this appears \[\e]0;\u@\h: \w\a\]${debian_chroot:+($debian_chroot)}\u@\h:\w\$ – luv.preet Jul 18 '17 at 07:34

    It is written in the question, sudo su from terminal – luv.preet Jul 18 '17 at 08:37

    Could you please open a new question if you have a new or follow-up question? If you tack hardly related questions onto existing questions you're broadening their scope which makes them harder to answer. On top of that it likely invalidates existing answers. I took the liberty to revert the edit that adds the follow-up question. Thanks. – David Foerster Jul 18 '17 at 09:46
