工作中，有时需要移植一些已经安装过的Solaris包，或者对已经安装后的包进行修改，但一时又无法找到原来的安装包。系统升级时，有时也常常涉及到对原来系统的备份问题，这时需要一些能够对原来的安装包进行备份，又能够在新系统上进行安装的工具。Solaris本身并不提供直接的工具用于包的移植。

但Solaris在安装本身通用的PKG包时，会产生两个与安装包相关的文档/上录，分别在/var/sadm/pkg/<pkgname>下和/var/sadm/install/contents中，通过对这两个文档进行解析，可以实现对Solaris包的反安装，这在实现系统升级时尤其有用。

以下脚本会在当前的运行目录下产生压缩的系统安装包，Copy/Paste本脚本到Solaris机上，运行后输入需要反安装的包名即可。欢迎大家测试。
