To do so, `adduser` command is often used. When it comes to multiple users' creation, `adduser` command may become boring and time-consuming. This short article intends to provide the Linux system administrator with a simple and unattended way for bulk user creation. The `newusers` command will help you to create multiple users by getting their info from a prefilled file. ### Requirements Privileged access to your Linux machine ### Conventions # - requires given command to be executed with root privileges either directly as a root user or by use of `sudo` command $ - given command to be executed as a regular non-privileged user ### How to proceed ### Create a file containing the usernames In this initial step, you need to create a file that will contain the list of the usernames that are to be created. ``` $ vi users-list.txt ``` Put in your file, one user info per line, following the pattern below: ``` Username:Password:User ID:Group ID:User Info:Home Directory:Default Shell Username:Password:User ID:Group ID:User Info:Home Directory:Default Shell Username:Password:User ID:Group ID:User Info:Home Directory:Default Shell ... ``` ### Create users After having created the previous file with predefined users info, use `newusers`command to create users. ``` # newusers users-list.txt ``` ### Check user accounts Finally you can confirm that the users were created correctly, by looking for their presence in the `/etc/passwd` file: ``` # tail /etc/passwd ``` ![using newusers for bulk user creation](https://linuxconfig.org/images/newusers-bulk-user-creation.png) -------------------------------------------------------------------------------- via: https://linuxconfig.org/simple-way-for-unattended-bulk-user-creation-in-linux 作者:[Essodjolo Kahanam][a] 译者:[译者ID](https://github.com/译者ID) 校对:[校对者ID](https://github.com/校对者ID) 本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译,[Linux中国](https://linux.cn/) 荣誉推出 [a]:https://linuxconfig.org/simple-way-for-unattended-bulk-user-creation-in-linux [1]:https://linuxconfig.org/simple-way-for-unattended-bulk-user-creation-in-linux#h4-1-create-a-file-containing-the-usernames [2]:https://linuxconfig.org/simple-way-for-unattended-bulk-user-creation-in-linux#h4-2-create-users [3]:https://linuxconfig.org/simple-way-for-unattended-bulk-user-creation-in-linux#h4-3-check-user-accounts [4]:https://linuxconfig.org/simple-way-for-unattended-bulk-user-creation-in-linux#h1-introduction [5]:https://linuxconfig.org/simple-way-for-unattended-bulk-user-creation-in-linux#h2-requirements [6]:https://linuxconfig.org/simple-way-for-unattended-bulk-user-creation-in-linux#h3-conventions [7]:https://linuxconfig.org/simple-way-for-unattended-bulk-user-creation-in-linux#h4-how-to-proceed
