Anti-installation implementation of the Sun Solaris installation package

At work, it is sometimes necessary to migrate some of the Solaris packages that have already been installed, or to modify the packages that have been installed, but cannot find the original installation package. When the system is upgraded, sometimes it often involves a backup problem for the original system, which requires some tools that can back up the original installation package and install on the new system. The Solaris itself does not provide a direct tool for package porting.

However, when Solaris installs its own generic pkg package, it produces two documents/records related to the installation package, respectively, in/var/sadm/pkg/and/var/sadm/install/contents, by parsing the two documents, You can implement a reverse installation of the Solaris package, which is especially useful when implementing a system upgrade.

The following script will produce a compressed system installation package in the current running directory, copy/paste to the Solaris machine, and then enter the name of the package you want to reverse install. Everyone is welcome to test.
