This project is a bash-based user management system created as part of a shell scripting course. It provides a menu-driven interface for managing users on a Linux system and includes error handling and permission checks.
The script supports the following user management operations:
- Show System Information
- List Users with
/bin/bashShell - Search for a User
- Add a New User
- Delete a User (with Home Directory Backup)
- Show User Details
- Change User Password
- Lock a User Account
- Unlock a User Account
- Exit the Program
Each operation is handled through individual functions for modularity and clarity.
- The menu reappears after each operation.
- Users can interactively choose actions from the list.
The script includes handling for the following edge cases:
- Invalid input detection
- User existence verification
- Backup directory validation
- Permission checks (
sudo/root requirement)
