Batch Processing

Batch Processing Example

    # Create some test files
    File("test_os_utils/file1.txt").write_text("Test file 1")
    File("test_os_utils/file2.txt").write_text("Test file 2")

    # Get file and directory objects
    file1 = os_utils.get_file("test_os_utils/file1.txt")
    dir1 = os_utils.get_directory("test_os_utils")

    print(f"File path: {file1.abspath}")
    print(f"Directory path: {dir1.abspath}")

    # Safe move operation
    os_utils.safe_move("test_os_utils/file1.txt", "test_os_utils/file1_moved.txt")
    print("File moved successfully")

    # Clean up
    test_dir.delete()

    """Demonstrate batch file processing."""
    print("\n=== Batch Processing ===")

    os_utils = OSUtils()

Secure Operations

Secure File Operations

    batch_dir.create()

    # Create test files
    files = []
    for i in range(3):
        file_path = f"batch_dir/batch_{i}.txt"
        File(file_path).write_text(f"Batch file {i}")
        files.append(file_path)

    # Define processing function
    def process_file(file_path):
        with open(file_path, 'r') as f:
            content = f.read()
        print(f"Processed {file_path}: {content}")

    # Process files in parallel
    print("\nProcessing files in parallel...")
    os_utils.batch_process(files, process_file, parallel=True)

File Search Operations

File Search Example

    batch_dir.delete()


def demo_secure_operations():
    """Demonstrate secure file operations."""
    print("\n=== Secure Operations ===")

    os_utils = OSUtils()
    secure_dir = Directory("secure_dir")
    secure_dir.create()

    # Create a file with sensitive content
    sensitive_file = File("secure_dir/sensitive.txt")
    sensitive_file.write_text("Sensitive data")

    # Securely delete the file
    print("Securely deleting file...")
    os_utils.safe_delete(sensitive_file.abspath, secure=True)
    print("File securely deleted")

    # Clean up
    secure_dir.delete()

Key Features

• Safe file and directory operations

• Parallel batch processing

• Secure file deletion

• Date-based file search

• Path manipulation

• Error handling and retry mechanisms

• Operation logging
