Sun Solaris 安裝包的反安裝實(shí)現(xiàn)

云知道

工作中，有時(shí)需要移植一些已經(jīng)安裝過的Solaris包，或者對(duì)已經(jīng)安裝后的包進(jìn)行修改，但一時(shí)又無法找到原來的安裝包 。系統(tǒng)升級(jí)時(shí)，有時(shí)也常常涉及到對(duì)原來系統(tǒng)的備份問題，這時(shí)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(shí)，會(huì)產(chǎn)生兩個(gè)與安裝包相關(guān)的文檔/上錄，分別在/var/sadm/pkg/下和/var/sadm/install/contents中，通過對(duì)這兩個(gè)文檔進(jìn)行解析，可以實(shí)現(xiàn)對(duì)Solaris包的反安裝，這在實(shí)現(xiàn)系統(tǒng)升級(jí)時(shí)尤其有用 。
以下腳本會(huì)在當(dāng)前的運(yùn)行目錄下產(chǎn)生壓縮的系統(tǒng)安裝包，Copy/Paste本腳本到Solaris機(jī)上，運(yùn)行后輸入需要反安裝的包名即可 。歡迎大家測試 。
