So, I finally got sick of typing my root user password in my Windows Subsystem for Linux (WSL), *nix Docker containers and Linux servers…

The answer (for some flavours of *nux): just create an addendum to /etc/sudoers by creating any new file in the /etc/sudoers.d/ directory!

Very simply:

• create a new file (e.g. sudoers) (I assume you know how to use vi, else just replace vi with text editor of choice as available!)

sudo vi /etc/sudoers.d/sudoers

• add the following line, replacing <user> as with the user name, then save and quit

<user> ALL=(ALL:ALL) NOPASSWD:ALL

Disconnect, re-connect with non-root account, type sudo bash and root away!
