+
+I'll create a Python script that uses argparse to parse a CSV file path, sorts a single line of comma-separated values alphabetically, and outputs the result to a file named "name_sorted.csv".
+
+```python
+#!/usr/bin/env python3
+import argparse
+import csv
+
+def main():
+    # Set up argument parser
+    parser = argparse.ArgumentParser(description='Sort a single-line CSV file alphabetically')
+    parser.add_argument('file_path', help='Path to the input CSV file')
+    
+    # Parse arguments
+    args = parser.parse_args()
+    
+    try:
+        # Read the input CSV file
+        with open(args.file_path, 'r') as file:
+            reader = csv.reader(file)
+            # Get the first line only
+            for row in reader:
+                values = row
+                break
+        
+        # Sort the values alphabetically
+        sorted_values = sorted(values)
+        
+        # Write to output file
+        with open('name_sorted.csv', 'w', newline='') as file:
+            writer = csv.writer(file)
+            writer.writerow(sorted_values)
+        
+        print(f"Successfully sorted values and saved to name_sorted.csv")
+        
+    except FileNotFoundError:
+        print(f"Error: File '{args.file_path}' not found")
+    except Exception as e:
+        print(f"Error: {e}")
+
+if __name__ == "__main__":
+    main()
+
+```
+
+This script:
+1. Uses argparse to get the input file path
+2. Opens the CSV file and reads only the first line
+3. Sorts the values alphabetically
+4. Writes the sorted values to "name_sorted.csv"
+
+To run the script, save it to a file (e.g., "sort_csv.py"), make it executable if needed, and run it with the path to your CSV file:
+
+```
+python sort_csv.py path/to/your/file.csv
+```
+
+Would you like me to explain any part of the code in more detail?
