 # User Management Solutions
 This section contains my solutions to various user management scenarios from the practice exercises.
 ## Scenario: Creating Users with Specific Requirements
 ### Original Problem
 From Practice Scenarios v3: Create a user named 'john' with a custom shell and home directory.
 ### Environment
 - OS Version: Rocky Linux 8.x
 - Initial State: No user 'john' exists
 - Required Outcome: User 'john' created with specific requirements
 ### Solution Steps
 1. Create the user with specific requirements
   ```bash
   # Create user with custom home directory
   sudo useradd -m -d /custom/home/john -s /bin/bash john
   # Set password
   sudo passwd john
   ```
   This creates the user 'john' with a custom home directory and bash shell
 2. Verify user creation
   ```bash
   # Check user entry in /etc/passwd
   grep john /etc/passwd
   # Verify home directory
   ls -la /custom/home/john
   ```
 ### Key Learnings
 - Understanding of useradd command options
 - Importance of verifying user creation
 - Best practices for user management
 ## Skills Demonstrated
 - User Account Management
 - Command Line Proficiency
 - Security Best Practices
 - System Verification
 [Additional scenarios will be documented here as they are completed]
