git如何创建交互式菜单？

#!/bin/bash

while true; do
    echo "1. Clone repository"
    echo "2. Pull changes"
    echo "3. Commit changes"
    echo "4. Exit"

    read -p "Please enter your choice: " choice

    case $choice in
        1)
            read -p "Please enter repository URL: " url
            git clone $url
            ;;
        2)
            git pull
            ;;
        3)
            read -p "Please enter commit message: " message
            git commit -m "$message"
            ;;
        4)
            break
            ;;
        *)
            echo "Invalid choice"
            ;;
    esac
done
