Linux users can be added with different ways. but one of the most used way is adding them throughout the shell because Linux admins loves shell usage. In this tutorial we will look how to add user into a Ubuntu, Kali, Mint, Debian box and provide or change required parameters. We will also look user deletion.
In order to add or remove user from a Linux box we need root privileges. We can get root privileges with different ways. We can login to root account like below.
$ su -
OR we can use
sudo command which operates given command with the current user but with root privileges.
$ sudo ls
Add User with adduser
We can use
adduser command in order to add user. We will add user named
poftut . This command will ask user detailes step by step. At the end of the process we will accept adding given user with
$ sudo adduser poftut
Add User with useradd
useradd is the fastest way to add user.
useradd will not look for any user detail. Just add user to the Linux box. But it will not configure any password for the given user so we should set recently added user password with
passwd like below. In this test we will add user named
test1 and change its password.
$ sudo useradd test2 $ sudo passwd test2
We can easily delete existing user with
userdel command. In the following example we will delete user named
test1 . We need root privileges again.
$ sudo userdel test2
