shell的圖形化實現簡單示例

shell指令碼一直以來就給人呆板枯燥的感覺。如果來點圖形的感覺可能大家對shell的感覺就會多加分。其實在linux中已經有人做了不少的工作，目前使用比較多的是dialog，還有很多衍生的版本，比如kdialog,gdialog,zenity等等。都在圖形介面上有自己的介面風格和特點。
安裝dialog，一般Linux中都會預設安裝這個包，如果沒有可以使用yum install來做。

[root@rac1 ~]# yum install dialog

Complete!

安裝完成後，我們來看看效果。dialog提供的選項功能還是很豐富的，自己也學習了個皮毛，簡單show一下。
 --&gtmsgbox元件
  dialog --msgbox 'this is test' 50 50

  dialog --title Testing --msgbox 'This is a new test by Jianrong' 10 20

 --yesno元件
  dialog --title "Please answer" --yesno "Do you want to have this testing " 10 20

 --inputbox元件
  dialog --inputbox "Enter your name" 10 20  Jianrong

 --fselect元件
  dialog --title "select a file " --fselect $HOME 10 20


更多的細節還有待學習提高。
