Add a sudo user to an Ubuntu system

January 25, 2019

code

# create a new user
# sudo useradd meowmeow -m -p '123badpassword'
sudo useradd meowmeow -m

# set password manually
sudo passwd meowmeow

# add to sudo
sudo usermod -aG sudo meowmeow

-m or --create-home creates the user's home dircetory
-p let's you set the password
-k or --skel adds skeleton files to home dircetory (you need to pass an argument). e.g. useradd meowmeow -m -k '/etc/skel/*'
-aG will append the the user to (supplimentary) group(s)

code

# TEST sudo powers
su meowmeow # switch to meowmeow

sudo apt update # try a sudo command

code

# manually copying skel files
sudo cp -r /etc/skel/.* /home/meowmeow

code

# remove the user and it's home dir
sudo userdel -r meowmeow
