RPM 规范文件查找已安装的版本

Question

安装 rpm 时我需要找到以前版本的软件包（如果已经安装）。我的规格文件如下

在POST

%post if [ "" = "1" ]; then # Perform new install fi elif [ "" = "2" ]; then # Perform update # what I need is value for Version if [ $Version = 1.0]; then # do upgrade 1 fi elif [ "$Version" = "2" ]; then #do upgrade 2 fi

fi

在上面的代码中，我如何获取版本的值。我尝试使用执行 rpm-qi | grep <rpm_package> 还有其他可用的方法吗？

不检查版本。检查数据是旧的还是新的。

%pre
grep OLDDATA /etc/myconfig >/dev/null && touch %{_localstatedir}/lib/rpm-state/%{name}.DoSomethingLater

%posttrans
if [ -e %{_localstatedir}/lib/rpm-state/%{name}.DoSomethingLater ]; then
# do some conditional stuff
rm -f %{_localstatedir}/lib/rpm-state/%{name}.DoSomethingLater
fi
