How to add a user in ubuntu 16.04 with only one single line with useradd

@ymeriergi

The shortest way would be:

useradd username

Where username is the username of the user you’re trying to add, i.e:

useradd sammy

After running the above command, a new basic user named sammy will be added to the system.

That said, the only adds a user to the system. That’s all that command is intended for, though there are a few other options, such as setting the users’ home directory, shell, etc.

Changes to the user can be done using usermod.

Let me know if that helps :-).
