shell的图形化实现简单示例

shell脚本一直以来就给人呆板枯燥的感觉。如果来点图形的感觉可能大家对shell的感觉就会多加分。其实在linux中已经有人做了不少的工作，目前使用比较多的是dialog，还有很多衍生的版本，比如kdialog,gdialog,zenity等等。都在图形接口上有自己的界面风格和特点。
安装dialog，一般Linux中都会默认安装这个包，如果没有可以使用yum install来做。

[root@rac1 ~]# yum install dialog

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。
