今天到網上搜ubuntu創建桌面快捷方式，發現盡是些不負責任，有問題的教程，故我也發教程一篇
在你的Home/Desktop文件夾下面新建一個xxx.desktop的文件，并且加上執行權限
chmod +x xxx.desktop
具體內容參照下面的模板，順便講一下linux下軟件的安裝方法，以sublime text 2為例
下載sublime linux的安裝包，在你的home目錄新建一個目錄名，可以叫app，或者myapps啥的，你自己明白就行，就是軟件的安裝目錄，把sublime text 2解壓到里面，于是整體的目錄結構如下
--home\yournam
----apps\
------sublime text 2\
下面解釋下模板的內容，第一行，是凡是標有可執行標記的腳本必備的注釋，內容為執行該腳本的解釋器地址，這里是解釋桌面快捷方式用的
第二行開始就是具體的內容了
解釋兩個重要的地方，地一個是exec，這個是你的可執行文件的地址，如果中間包含空格，那么用引號擴起來
Icon，這個是你的應用的圖標，要不默認圖標很難看
#!/usr/bin/env xdg-open
