Ubuntu is popular for having multiple users as it mainly is a Multi-user Operating System. Creating new users is essential for administrators as instead of one user having all the administrative privileges, multiple users are created for more access control and authorization of users. With each user having a separate account, user management can be carried out by the administrator effortlessly and the administrator can then monitor every individual account as well.<\/p>\n

In this article, the different methodologies and approaches to creating a user account are explained.<\/p>\n

What is the Newusers Command in Linux\/Ubuntu?<\/strong><\/h2>\n

The \u201cnewusers\u201d and the \u201cuseradd\u201d are valuable commands in Ubuntu used mostly by administrators to create new users. The new users can be made in Bulk, i.e. Recursively, and a single user at a time. New users can be created in multiple ways and each method for creating a new user or creating multiple users is explained below.<\/p>\n

Method 1: Creating New Users With Default Configuration<\/strong><\/h3>\n

The \u201cuseradd\u201d command can be used to create a new user in Ubuntu with the default configuration. With the default configuration, the newly created user will have the group of the same username, default home directory, and the default \u201c\/bin\/sh\u201d shell. To create a new user with \u201cuseradd\u201d, use the command:<\/p>\n

useradd <<\/span>userName><\/span><\/div><\/div>\n

In our case, to create a new user \u201cumar\u201d with \u201cuseradd\u201d, the command used will be:<\/p>\n

sudo<\/span> useradd umar<\/div><\/div>\n

The terminal will move to the next line once the user is created indicating the success of user creation:<\/p>\n

<\/p>\n

The new user added can be verified using the command:<\/p>\n

cat<\/span> \/<\/span>etc\/<\/span>passwd<\/span><\/div><\/div>\n

All the users will be displayed in the terminal. Scroll down and you will find the newly created user with the default configuration:<\/p>\n

<\/p>\n

As the new user was created with the default configuration, the password needs to be added for the new user \u201cumar\u201d. The password for the newly created user, in our case \u201cumar\u201d, can be added using the command:<\/p>\n

sudo<\/span> passwd<\/span> umar<\/div><\/div>\n

The New Password will be asked in the command line:<\/p>\n

<\/p>\n

Following the addition of a New Password, the command line will ask you to retype the password for confirmation. Once the password matches, it will inform that the new user password has been updated successfully:<\/p>\n

<\/p>\n

Method 2: Creating New Users with Custom Configuration<\/strong><\/h2>\n

New users with Custom Configuration can also be created using the \u201cuseradd\u201d command. For the Custom Configuration, you need to pass the configuration parameters in the command line:<\/p>\n

useradd -s<\/span> <<\/span>shell><\/span> -m<\/span> -d<\/span> <<\/span>home-directory><\/span> -g<\/span> <<\/span>groupName><\/span> <<\/span>userName><\/span><\/div><\/div>\n

Here, the \u201c-s <shell>\u201d is for the users\u2019 login shell, \u201c-m\u201d will create the home directory if it does not exist, and the \u201c-d <home-directory>\u201d is for adding the Custom Home Directory of the user.<\/p>\n

In our case, we will create a new user with custom configurations using the \u201cuseradd\u201d command. The new user, in our case \u201chashaam\u201d, will have the custom shell \u201c\/bin\/sh\u201d, the custom home directory \u201c\/home\/nyc\u201d and the group \u201cgenz\u201d:<\/p>\n

sudo<\/span> useradd -s<\/span> \/<\/span>bin\/<\/span>sh<\/span> -m<\/span> -d<\/span> \/<\/span>home\/<\/span>nyc -g<\/span> genz hashaam<\/div><\/div>\n

The cursor moves to the next line indicating the new user was created successfully:<\/p>\n

<\/p>\n

The newly created user \u201chashaam\u201d can be verified by using the command:<\/p>\n

grep<\/span> hashaam \/<\/span>etc\/<\/span>passwd<\/span><\/div><\/div>\n

The \u201cgrep\u201d will filter the users’ list and return only the details of the user \u201chashaam\u201d:<\/p>\n

<\/p>\n

Method 3: Creating New Users Collectively<\/strong><\/h2>\n

To create New users recursively the \u201cadduser\u201d command is used in Ubuntu. The \u201cadduser\u201d command is more favorable as it asks for the user configuration parameters while creating the new user. The \u201cadduser\u201d command in Ubuntu is used in a simple way using the command followed by the user name of the new user:<\/p>\n

adduser <<\/span>userName><\/span><\/div><\/div>\n

In our case, to create a new user \u201cmike\u201d using \u201cadduser\u201d, the command used will be:<\/p>\n

sudo<\/span> adduser mike<\/div><\/div>\n

It will start creating the user and will ask for the user configuration parameters detail one by one:<\/p>\n

<\/p>\n

Once you have added the details, in our case, for the user \u201cmike\u201d, it will ask for confirmation. Enter \u201cY\u201d to create the new user:<\/p>\n

<\/p>\n

The new user will be created and can be verified using the \u201cgrep\u201d command with the user name.<\/p>\n

grep<\/span> mike \/<\/span>etc\/<\/span>passwd<\/span><\/div><\/div>\n

The \u201cgrep\u201d command will filter the user list and return only the details of the new user \u201cmike\u201d:<\/p>\n

<\/p>\n

 <\/p>\n

Method 4: Creating New Users in Bulk<\/strong><\/h2>\n

The \u201cnewusers\u201d command is a useful command for creating multiple users in bulk. It makes the process of creating new users unchallenging and time-saving for the administrators. To create new users in bulk, you have to create a new text file first which will have the configuration details of all the new users. In our case, to create a new text file \u201cbulk-users.txt\u201d the nano command is used:<\/p>\n

sudo<\/span> nano<\/span> bulk-users.txt<\/div><\/div>\n

This will create the new text file and will open the Text Editor:<\/p>\n

<\/p>\n

Inside the text editor, the configuration of the new users is to be added. The configuration parameters of users as how they are stored in the system are:<\/p>\n

<<\/span>loginName><\/span> : <<\/span>password><\/span> : <<\/span>UID><\/span> : <<\/span>GroupID><\/span> : <<\/span>comment><\/span> : <<\/span>home-directory><\/span> : <<\/span>shell><\/span><\/div><\/div>\n

In our case, to add three new users \u201cbobby\u201d, \u201cjohn\u201d, and \u201caswan\u201d according to the user configuration format, the configuration parameters added in the text editor will be:<\/p>\n

bobby:password123:1009<\/span>:1009<\/span>:BobbyID:\/<\/span>home\/<\/span>bobby1:\/<\/span>bin\/<\/span>sh<\/span>
\njohn:password123:1012<\/span>:1012<\/span>:JohnID:\/<\/span>home\/<\/span>john1:\/<\/span>bin\/<\/span>sh<\/span>
\naswan:password123:1022<\/span>:1022<\/span>:AswanID:\/<\/span>home\/<\/span>aswan1:\/<\/span>bin\/<\/span>sh<\/span><\/div><\/div>\n

Once the new user configurations are added, write them into the text editor using the shortcut key \u201cctrl+o\u201d:<\/p>\n

<\/p>\n

Hit \u201cEnter\u201d to write the content to the text file and then close the text editor using the \u201cctrl+x\u201d key. Now, to add these bulk users in Ubuntu use the \u201cnewusers\u201d command:<\/p>\n

sudo<\/span> newusers bulk-users.txt<\/div><\/div>\n

The command line moves to the next line indicating the users are added:<\/p>\n

<\/p>\n

To verify the newly created users, use the \u201ccat\u201d command to list all the users:<\/p>\n

cat<\/span> \/<\/span>etc\/<\/span>passwd<\/span><\/div><\/div>\n

In the users’ list, scroll down to the end and you will see the newly created users. In our case, all three users were created:<\/p>\n

<\/p>\n

Conclusion<\/strong><\/h2>\n

The \u201cnewusers\u201d and the \u201cadduser\u201d commands are helpful commands for creating new users in Ubuntu. With these commands, the administrator or any sudo user can create new users with either default configuration or custom configuration. These commands can also create new users collectively as well as multiple new users in Bulk. This article has explained the use of both these commands for creating new users in a variety of different ways.<\/p>\n
