Solaris 實現(xiàn)安裝包的反安裝

云知道


工作中，有時需要移植一些已經(jīng)安裝過的Solaris包，或者對已經(jīng)安裝后的包進(jìn)行修改，但一時又無法找到原來的安裝包 。系統(tǒng)升級時，有時也常常涉及到對原來系統(tǒng)的備份問題，這時需要一些能夠?qū)υ瓉淼陌惭b包進(jìn)行備份，又能夠在新系統(tǒng)上進(jìn)行安裝的工具 。Solaris本身并不提供直接的工具用于包的移植 。

但Solaris在安裝本身通用的PKG包時，會產(chǎn)生兩個與安裝包相關(guān)的文檔/上錄，分別在/var/sadm/pkg/【Solaris 實現(xiàn)安裝包的反安裝】下和/var/sadm/install/contents中，通過對這兩個文檔進(jìn)行解析，可以實現(xiàn)對Solaris包的反安裝，這在實現(xiàn)系統(tǒng)升級時尤其有用 。

以下腳本會在當(dāng)前的運行目錄下產(chǎn)生壓縮的系統(tǒng)安裝包，Copy/Paste本腳本到Solaris機上，運行后輸入需要反安裝的包名即可 。歡迎大家測試 。
