内容二：case 语句的使用案例
2.1 直接使用 case 语句的案例
#!/bin/bash
read -p "Which one do you like better, eternalcenter eternalcentre ec-x : " name
case $name in
eternalcenter)
echo "Do you realy like $name better? eternalcenter?" ;;
eternalcentre)
echo "Do you realy like $name better? eternalcentre?" ;;
ec-x)
echo "Do you realy like $name better? ec-x?" ;;

esac
2.2 用变量作为条件判断使用 case 语句的案例
#!/bin/bash
read -p "Which one do you like better, eternalcenter eternalcentre ec-x : " name
Variable1=eternalcenter
Variable2=eternalcentre
Variable3=ec-x
case $name in
$Variable1)
echo "Do you realy like $name better? eternalcenter?" ;;
$Variable2)
echo "Do you realy like $name better? eternalcentre?" ;;
$Variable3)
echo "Do you realy like $name better? ec-x?" ;;
*)
echo "So you don't like them all ." ;;
esac
