shell case 语句示例

Sure, I can help with that! Here's an example of a shell case statement in Bash:

read -p "What is your favorite color? " color

case $color in
  red)
    echo "Red is a great color!"
    ;;
  blue)
    echo "Blue is also a nice color."
    ;;
  green)
    echo "Green is a good choice."
    ;;
  *)
    echo "Hmm, I'm not sure what color that is."
    ;;
esac

This script prompts the user for their favorite color, and then uses a case statement to choose a response based on their input. If the user enters "red", the script will output "Red is a great color!", and so on. The final `*)` case is the "default" case that will match anything that doesn't match the previous cases.
