enable NOPASSWD for yourself

I have some bash scripts which I manually run a lot and they need to run with sudo. I also don’t want to be prompted for any password. Here is the solution.

1. Edit the /etc/sudoers:

   $ sudo vi /etc/sudoers

2. Add a new entry at the last (USERNAME is your account name).

   # 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
   USERNAME        ALL=(ALL:ALL)   NOPASSWD:ALL
   
   # See sudoers(5) for more information on "#include" directives:
   
   #includedir /etc/sudoers.d
   

3. Restart the sudo service.

   $ sudo service sudo restart

4. Logout then login again. You won’t be prompted for the password anymore.
