我注意到，对于这样简单的用户输入，没有人发布显示多行回声菜单的答案，所以我的做法如下：

#!/bin/bash

function ask_user() {    

echo -e "
#~~~~~~~~~~~~#
| 1.) Yes    |
| 2.) No     |
| 3.) Quit   |
#~~~~~~~~~~~~#\n"

read -e -p "Select 1: " choice

if [ "$choice" == "1" ]; then

    do_something

elif [ "$choice" == "2" ]; then

    do_something_else

elif [ "$choice" == "3" ]; then

    clear && exit 0

else

    echo "Please select 1, 2, or 3." && sleep 3
    clear && ask_user

fi
}

ask_user

发布这种方法是希望有人发现它有用且省时。

echo "Please enter some input: "
read input_variable
echo "You entered: $input_variable"

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

您需要：

Bash内置命令（即便携式）检查TTY默认答案超时彩色问题

一小条

do_xxxx=y                      # In batch mode => Default is Yes
[[ -t 0 ]] &&                  # If TTY => Prompt the question
read -n 1 -p $'\e[1;32m
Do xxxx? (Y/n)\e[0m ' do_xxxx  # Store the answer in $do_xxxx
if [[ $do_xxxx =~ ^(y|Y|)$ ]]  # Do if 'y' or 'Y' or empty
then
    xxxx
fi

解释

[[-t 0]]&&read…=>如果TTY，调用命令读取read-n 1=>等待一个字符$'\e[1；32m…\e[0m'=>绿色打印（绿色很好，因为在白色/黑色背景上都可以阅读）[[$do_xxxx=~^（y|y|）$]]=>bash正则表达式

超时=>默认答案为否

do_xxxx=y
[[ -t 0 ]] && {                   # Timeout 5 seconds (read -t 5)
read -t 5 -n 1 -p $'\e[1;32m
Do xxxx? (Y/n)\e[0m ' do_xxxx ||  # read 'fails' on timeout
do_xxxx=n ; }                     # Timeout => answer No
if [[ $do_xxxx =~ ^(y|Y|)$ ]]
then
    xxxx
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：

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
}
