Ubuntu: sudo without password prompt

How many of you are bored of typing your password every time you run a sudo command on your personal computer?! This is a bloody waste of time! I mean, I appreciate the sudoer jazz and the importance of security but then this is my freaking single-owner-only laptop! Why do I need to type password everytime I run a command with a sudo? In fact, if someone has a shell access to my laptop then my biggest worry is ‘where did I lose my laptop?’ more than ‘oh! crap! There is no sudo password!’ Right? How many with me on this one? 🙂

Anyways, so here is my attempt to eradicate password prompt for sudo on my personal laptop. And, it turned out to be super simple! 🙂

Please run this at the command line to edit the sudo list:

$> sudo visudo

The content before I modified is as below:

#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.
#
Defaults env_reset
Defaults mail_badpass
Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

# Host alias specification

# User alias specification

# Cmnd alias specification

# User privilege specification
root ALL=(ALL:ALL) ALL

# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL

# Allow members of group sudo to execute any command
%sudo ALL=(ALL:ALL) ALL

# See sudoers(5) for more information on "#include" directives:

#includedir /etc/sudoers.d

Now, append the following line to the END of the file (if not at the end there is a chance it could be nullified by other entries!):

<username> ALL=NOPASSWD: ALL

In my case, this is:

rp ALL=NOPASSWD: ALL

Save & exit!

To enforce this “no-password-sudo” rule, logout & log back in and Voila you are done! 🙂
