--title “Email Manager” 是标题,双引号里是自己填的提示信息
--nocancel 是在这个图文里面不显示取消,只显示OK
--menu “Choose your option” 15 60 4 是表示菜单提示,双引号里是自己填的提示信息,15是高度,60是长度,4是有个选择项目
下面的1-4是自己的提示
最后比较关键,3》&1 1》&2 2》&3是为了把选择的内容填进变量OPTION
whiptail --title “EmailAddress-form Input Box” --inputbox “What is your add EmailAddress?” 10 60 @shenxu.com 3》&1 1》&2 2》&3
--inputbox “What is your add EmailAddress?” 是可以形成一个让用户输入的提示框
@shenxu.com 是默认输入text里的值
whiptail --msgbox “You chose Cancel.” 10 40 是显示一行你的提示
其实还有--infobox,似乎和msgbox很像,其实不同,它基本上用不上,是在shell运行完后,可以往前翻页能看见的东西
--scrolltext 20 40是为了显示多行的时候可以上下滚动
另外还有--passwordbox和text一样输入,就是以***显示
whiptail --checklist “choose” 15 60 2 “1” “aa” ON “2” “bb” ON
15 60还是高和宽,2是有几个选项,和menu一样,后面多了一个ON或者OFF表示状态,就是菜单出来后默认是不是选,On是选,OFF不选,用空格键来选择。可以多选。
--radiolist,不可以多选了。ON就只能有一个,其它必须是OFF
还有一个显示进度条的--gauge,我觉得没啥用处。
#!/bin/bash
{
for n in `seq 100`
do
sleep 1
echo $n
done
} | whiptail --gauge “Please wait while installing” 6 60 0
以上就是Linux使用whiptail形成对话框的方法,把写好的代码复制到whiptail里面就可以形成对话框了。
