安装完成后，我们来看看效果。dialog提供的选项功能还是很丰富的，自己也学习了个皮毛，简单show一下。-->msgbox组件
dialog --msgbox 'this is test' 50 50
dialog --title Testing --msgbox 'This is a new test by Jianrong' 10 20
--yesno组件
dialog --title "Please answer" --yesno "Do you want to have this testing " 10 20
--inputbox 组件
dialog --inputbox "Enter your name" 10 20 Jianrong
--fselect组件
dialog --title "select a file " --fselect $HOME 10 20
更多的细节还有待学习提高。
