Add Sudo Privileges to User

How to Add User to Sudoers in UbuntuLinuxize

Adding User to the sudo Group

usermod -aG sudo username

Adding User to the sudoers File

EDITOR=nano visudo

No password required

/etc/sudoers

username  ALL=(ALL) NOPASSWD:ALL

Limit allowed commands

In the following example, username would only be allowed to use commands mkdir and rmdir without a password. All other commands would require a password for sudo

/etc/sudoers

username ALL=(ALL) ALL
username ALL=(ALL) NOPASSWD:/bin/mkdir,/bin/rmdir

Add via seperate sudoers file

The /etc/sudoers.d/ directory allows the use of seperate drop in configuration files if you do not want to edit the main /etc/sudoers file itself.

echo "username  ALL=(ALL) ALL" | sudo tee /etc/sudoers.d/username
