It's critical for sysops engineers to adopt the habit of effectively managing user accounts, particularly when onboarding new clients, users, or staff members. This post will walk you through the process of writing a Bash script that adds users, adds them to groups, generates passwords, and logs all of your activities automatically. This module is a component of the HNG Devops Track job. To start working practically with devops and all of its relevant stacks, HNG is a great place to start. Applying is possible, or you can learn more at https://hng.tech/internship. Now let's begin the assignment for today.
Overview
Handling user accounts by hand can be laborious and prone to mistakes. This procedure needs to be automated for consistency, time savings, and reduced mistake. Using a file containing a list of usernames and groups, we will develop a script named "create_users.sh" that creates users and groups, configures their home directories, generates random passwords, and logs all tasks, actions, and errors to a management.log file.
Prerequisites:
It is essential that you possess the following knowledge before we start; if not, please review previous modules to familiarize yourself with the ideas;
1.Basic familiarity with Linux commands
2.Rights to administer the system and
3.A text editor (such as vim, nano, etc.)
Summary
The following tasks are completed by the script:
1.reads from a file a list of users and groups.
2.establishes users and places them in designated groups.
3.creates home directories and grants the necessary access.
4.creates passwords at random for users.
5.records every operation in the file /var/log/user_management.log.
6./var/secure/user_passwords.csv is where the created passwords are safely stored.
Script Breakdown
Below is a breakdown of the complete script with explanations.
Bash shells are commonly found on Linux operating systems. In this article, we will be working primarily with Ubuntu, a Linux distribution. You can download and set up Ubuntu here: (Canonical Ubuntu)[http://ubuntu.com/download].
Once you have your terminal open, you should see a prompt like the one below:
