Create a User on Linux

To create a default admin user on Linux, you can follow these steps:

First, you need to create a new user account using the useradd command. For example, you can create a user named “admin” with the command sudo useradd admin.
Next, you need to set a password for the new user using the passwd command. For example, you can set the password for the “admin” user with the command sudo passwd admin.
To grant the new user administrative privileges, you need to add them to the sudo group. You can do this using the usermod command with the -aG option. For example, you can add the “admin” user to the sudo group with the command sudo usermod -aG sudo admin.
Finally, you can verify that the new user has administrative privileges by logging in as the “admin” user and running a command that requires root privileges, such as sudo apt-get update.
Here is an example of how you can create a default admin user on a Linux system:

sudo useradd admin
sudo passwd admin
sudo usermod -aG sudo admin
mkhomedir_helper admin

Or, in a one-liner

sudo useradd -m -G sudo -U -s /bin/bash admin
