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

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：

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

用最少的行数实现这一点的最简单方法如下：

read -p "<Your Friendly Message here> : y/n/cancel" CONDITION;

if [ "$CONDITION" == "y" ]; then
   # do something here!
fi

if只是一个例子：如何处理这个变量取决于您。

inquire ()  {
  echo  -n "$1 [y/n]? "
  read answer
  finish="-1"
  while [ "$finish" = '-1' ]
  do
    finish="1"
    if [ "$answer" = '' ];
    then
      answer=""
    else
      case $answer in
        y | Y | yes | YES ) answer="y";;
        n | N | no | NO ) answer="n";;
        *) finish="-1";
           echo -n 'Invalid response -- please reenter:';
           read answer;;
       esac
    fi
  done
}

... other stuff

inquire "Install now?"

多选版本：

ask () {                        # $1=question $2=options
    # set REPLY
    # options: x=..|y=..
    while $(true); do
        printf '%s [%s] ' "$1" "$2"
        stty cbreak
        REPLY=$(dd if=/dev/tty bs=1 count=1 2> /dev/null)
        stty -cbreak
        test "$REPLY" != "$(printf '\n')" && printf '\n'
        (
            IFS='|'
            for o in $2; do
                if [ "$REPLY" = "${o%%=*}" ]; then
                    printf '\n'
                    break
                fi
            done
        ) | grep ^ > /dev/null && return
    done
}

例子：

$ ask 'continue?' 'y=yes|n=no|m=maybe'
continue? [y=yes|n=no|m=maybe] g
continue? [y=yes|n=no|m=maybe] k
continue? [y=yes|n=no|m=maybe] y
$

它会将REPLY设置为y（在脚本中）。
