Password-less sudo

January 25, 2022 Tech linux sudo

While never a good idea to enable this in a production, or multi-user system, on a lab system, not needing to type in a password when running sudo makes life a lot easier.

To enable password-less sudo:
```
sudo visudo
```
Add this to the bottom of the file, assuming your username is tom:
```
tom ALL=(ALL) NOPASSWD: ALL
```
If we wanted to add a group, instead of a user:
```
docker ALL=(ALL) NOPASSWD: ALL
```
This example would allow any user for the docker group to run sudo without a password.
If we wanted the user tom to be able to run apt without a password:
```
tom ALL=(ALL) NOPASSWD: /usr/bin/apt
```
