Ubuntu: Create user directory afterwards

If you create an new user with useradd without using the option -m there will be created no home directory

Create user without -m

sudo useradd testuser

Create home directory manually by copying the template of /etc/skel

sudo cp -r /etc/skel /home/testuser

Set owner of /home/testuser

sudo chown -R testuser:testuser /home/testuser

Set GECOS-field / comment after user was created

sudo usermod -c "Test User"

When creating a user with useradd the default shell is set to dash (/bin/sh). We will change this to bash

sudo usermod -s /bin/bash

Without password the user will not be available at logon. So we will set one

sudo passwd testuser
