Question

说我有以下内容：

echo "Would you like to blarg, or flarg?"
read -e ACT

if [ "$ACT" == "blarg" ]
then
echo "Go Blarg."
echo "Possible Blargs are Blah and Flah, or go back to the previous question."
    read -e MARV
fi

if [ "$ACT" == "flarg" ]
then
echo "Go Flarg."
echo "Possible Flargs are Blah and Flah, or go back to the previous question."
    read -e CARVE
fi
    (more if statements following general pattern)

我需要知道怎样做back来回答上一个问题（Blah或Flah）来自MARV或CARVE的答案，以及回到第一个（Flarg或Blarg）。

编辑：我实际上需要知道如何使用read重新定义变量。男孩，我是否可以过度思考。

Answer 1

你的意思是：

while ! [[ "${ACT-}" =~ [bf]larg ]]
do
    read -e ACT
    [...]
done

返回bash中的前一个if语句
