首先描述下我的环境， 喜欢折腾着玩，所以我的电脑上装了3个系统，分别是ubuntu22.04, opensuse 15.5, manjora 三个操作系统，平时基本上换着用。这3个系统分别使用独立的根分区/ 和 /root分区， 但挂载同一个数据分区 /u01(存放数据文件和软件等)
这3个操作系统上都装上了我平时经常使用的软件，像libreoffice，typora等。
之前， 需要分别在ubuntu上安装软件的deb版本， 在opensuse上安装软件的rpm版本， 在manjaro上安装软件的二进制版本。
后来发现很多linux软件有appimage版本，不需安装就能运行。 例如 navicat ， 也有的软件只要解压就可以运行，例如 idea。
所以， 我就开始摒弃rpm/deb 版本 ，转而下载appimage和二进制压缩包了， 这样只要在 /usr/share/applications 中按照格式创建 .desktop文件，开始菜单中就有对应的图标了，打开就是执行，非常方便。
这样就不用分别为3个系统安装deb/rpm/binary包了。 只需要写好脚本，安装完操作系统，运行下脚本，分别为软件创建.desktop就行了。
大部分.desktop文件是大同小异，主要的就2项，一个是程序的路径， 一个是程序的图标。为了和rpm/deb安装效果一样， 我参考了rpm/deb安装生成的 .desktop文件内容， 并从appimage中提取了原版的图标。写下了下面的创建脚本， 供大家参考。
分三部分，分别是libreoffice， appimage软件， 二进制压缩包软件。
linux上如何创建软件快捷方式图标
linux上如何创建appimage软件快捷方式
linux上如何创建二进制包软件快捷方式图标
libreoffice
libreoffice软件包含了writer，calc，math，impress ,base,draw等等， 分别对应office中的word，excel，powerpoint ,access,viso 等软件。还有math(公式编辑器) 没有对应的office产品，libreoffice相当于入口。所以一共要创建7个快捷方式。
写法稍微复杂，单独列出来。ubuntu22.04/opensuse 15.5 /manjaro均测试通过
