Bulk User Creator (Linux)
Description
This script automates the bulk creation of user accounts on a Linux system. It prompts for the username and the number of users to create. Usernames are generated based on the input and stored in a CSV file. Each user is created with a default password that matches their username.
Requirements
- Linux environment
-
useraddcommand available - To encrypt the password of the users using
mkpasswd, is it necesarry to installwhoisPacket.
sudo apt install whois
Installation
- Clone the repository:
git clone https://github.com/ciscoAnass/Bulk-Linux-User.git
cd Bulk-Linux-User
- Make the script executable:
chmod +x BulkUsers.sh
Creating a Command Alias (Optional but recommended)
- Add the following line to your shell configuration file (e.g., ~/.bashrc for bash):
echo "alias bulkuser='sudo ~/Bulk-Linux-User/BulkUsers.sh'" >> ~/.bashrc
Then, apply the changes:
source ~/.bashrc
Usage
Now you can use the bulkuser alias in your terminal to run the script with parameters. Here's how:
- To create 7 users with the username "poppy" (You can choose whatever Username you want to create , also numbers):
bulkuser poppy 7
- This will generate output similar to:
User : poppy1 , Password : poppy1
User : poppy2 , Password : poppy2
User : poppy3 , Password : poppy3
User : poppy4 , Password : poppy4
User : poppy5 , Password : poppy5
User : poppy6 , Password : poppy6
User : poppy7 , Password : poppy7
- Additionally, it will create a UsrAccess-poppy.csv file containing the usernames and passwords.
Verification
To verify that the users have been created correctly, follow these steps:
- Check User Accounts: List the last 7 users created on the system to ensure they have been created:
getent passwd | tail -7 | cut -d: -f1
Notes
- Ensure you have the necessary permissions to execute user creation commands (useradd).
- Consider security implications when using default passwords.
