此解决方案读取单个字符，并在yes响应时调用函数。

read -p "Are you sure? (y/n) " -n 1
echo
if [[ $REPLY =~ ^[Yy]$ ]]; then
    do_something      
fi

要获得像inputbox这样的漂亮ncurses，请使用如下命令对话框：

#!/bin/bash
if (dialog --title "Message" --yesno "Want to do something risky?" 6 25)
# message box will have the size 25x6 characters
then 
    echo "Let's do something risky"
    # do something risky
else 
    echo "Let's stay boring"
fi

默认情况下，对话框包至少在SUSE Linux上安装。看起来像：

我建议你使用对话框。。。

Linux学徒：使用对话框改进Bash Shell脚本对话框命令允许在shell脚本中使用窗口框，以使其使用更具交互性。

它简单易用，还有一个名为gdialog的gnome版本，它采用了完全相同的参数，但在X上显示了GUI风格。

更通用的是：

function menu(){
    title="Question time"
    prompt="Select:"
    options=("Yes" "No" "Maybe")
    echo "$title"
    PS3="$prompt"
    select opt in "${options[@]}" "Quit/Cancel"; do
        case "$REPLY" in
            1 ) echo "You picked $opt which is option $REPLY";;
            2 ) echo "You picked $opt which is option $REPLY";;
            3 ) echo "You picked $opt which is option $REPLY";;
            $(( ${#options[@]}+1 )) ) clear; echo "Goodbye!"; exit;;
            *) echo "Invalid option. Try another one.";continue;;
         esac
     done
     return
}

使用read命令：

echo Would you like to install? "(Y or N)"

read x

# now check if $x is "y"
if [ "$x" = "y" ]; then
    # do something here!
fi

然后你需要的所有其他东西

yn() {
  if [[ 'y' == `read -s -n 1 -p "[y/n]: " Y; echo $Y` ]];
  then eval $1;
  else eval $2;
  fi }
yn 'echo yes' 'echo no'
yn 'echo absent no function works too!'
