rpm -F和rpm -U有什麼區別？

Question

我正在通過rpm的手冊頁，但可以得到rpm -F和rpm -U之間的確切區別。
任何人都可以請我幫忙嗎？

Answer 1

-F|--freshen僅安裝系統上已安裝的軟件包的更新。所以

rpm -U already-installed-package.2.0.rpm 
rpm -F already-installed-package.2.0.rpm 

相當，但

rpm -U not-installed-package.2.0.rpm # will install 
rpm -F not-installed-package.2.0.rpm # won't install 

都沒有。

從該名男子頁：

轉{-U | --upgrade} [安裝選項] ... PACKAGE_FILE

This upgrades or installs the package currently installed to a newer version. This is the same as install, except all other 

包的版本（或多個）後取出新包裝安裝了 。

rpm {-F|--freshen} [install-options] PACKAGE_FILE ... 

    This will upgrade packages, but only ones for which an earlier version is installed.
