今天到网上搜ubuntu创建桌面快捷方式，发现尽是些不负责任，有问题的教程，故我也发教程一篇

在你的Home/Desktop文件夹下面新建一个xxx.desktop的文件，并且加上执行权限

chmod +x xxx.desktop

具体内容参照下面的模板，顺便讲一下linux下软件的安装方法，以sublime text 2为例

下载sublime linux的安装包，在你的home目录新建一个目录名，可以叫app，或者myapps啥的，你自己明白就行，就是软件的安装目录，把sublime text 2解压到里面，于是整体的目录结构如下

--homeyournam

----apps

------sublime text 2

下面解释下模板的内容，第一行，是凡是标有可执行标记的脚本必备的注释，内容为执行该脚本的解释器地址，这里是解释桌面快捷方式用的

第二行开始就是具体的内容了

解释两个重要的地方，地一个是exec，这个是你的可执行文件的地址，如果中间包含空格，那么用引号扩起来

Icon，这个是你的应用的图标，要不默认图标很难看

#!/usr/bin/env xdg-open
