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
}

受到@Mark和@Myrdin的回答的启发，我创建了一个通用提示的函数

uniprompt(){
    while true; do
        echo -e "$1\c"
        read opt
        array=($2)
        case "${array[@]}" in  *"$opt"*) eval "$3=$opt";return 0;; esac
        echo -e "$opt is not a correct value\n"
    done
}

这样使用：

unipromtp "Select an option: (a)-Do one (x)->Do two (f)->Do three : " "a x f" selection
echo "$selection"

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

您可以使用内置的read命令；使用-p选项向用户提示问题。

从BASH4开始，您现在可以使用-i建议答案：

read -e -p "Enter the path to the file: " -i "/usr/local/etc/" FILEPATH
echo $FILEPATH

（但请记住使用“readline”选项-e以允许使用箭头键进行行编辑）

如果你想要一个“是/否”的逻辑，你可以这样做：

read -e -p "
List the content of your home dir ? [Y/n] " YN

[[ $YN == "y" || $YN == "Y" || $YN == "" ]] && ls -la ~/

我为回答是/否问题编写了一个小脚本：https://github.com/optimistiCli/getans

例子：

#!/bin/bash

if ! getans.sh 'Shall we proceed?' y ; then
    echo "User said “NO”"
    exit 1
fi

echo "User said “YES”"
# do something usefull
exit 0

Bash为此选择了。以下是如何在脚本中使用它：

select result in Yes No Cancel
do
    echo $result
done

这是它使用的样子：

$ bash examplescript.sh
1) Yes
2) No
3) Cancel
#? 1
Yes
#? 2
No
#? 3
Cancel
#?
