Question

我试图在unix中创建一个会话，这将允许我提出一个简单的问题，然后根据答案提出不同的问题。例如，如果我要问＆＃39;输入选择（退出/订购）＆＃39;

如果＆＃39;退出＆＃39;输入然后程序应该关闭如果＆＃39;命令＆＃39;输入后，程序应继续询问其他问题。

如果你能提供帮助那就太好了！谢谢！

Answer 1

#!/bin/bash

echo "Lots of choices.."
read -p "What is your choice? " choice

echo "Your choice was $choice"

if [ $choice == "quit" ]
then
echo "Exiting.."; exit 0
fi

if [ $choice == "order" ]
then
echo "Doing some other stuff.."
fi

Answer 2

这是shell的select命令派上用场的地方。我假设你正在使用bash

PS3="Enter a choice: "
select answer in Quit Order; do
    case $answer in
        Quit) echo "Thanks for playing."; exit ;;
        Order) 
            # select is like an infinite loop: you need to break out of it
            break
            ;;
        *) echo "Use the numbers to select your answer." ;;
    esac
done
