Question

我想在卸载时在客户端打印消息，如果错误然后我总是打印，如果它是简单的消息，如rpm卸载成功那么它是可选的.client使用选项-v然后它打印（详细其他明智不）

rpm -ivh xyz.rpm for install and rpm -ev xyz for uninstall as below.

#Pre-Uninstall部分

%preun
Processes=`ps -Ao"%p:%a"  --cols 150 |
 egrep "Launcher|rmiregistry" | grep -v grep | cut -d ":" -f1`
         if [ -n "$Processes" ]; then
                echo 'xyz is running ,first stop it then uninstall.' > /dev/stderr;
                exit 1;
         else
                 echo 'xyz service is not running' >/dev/stdout;
         fi

目前上面的代码打印每次rpm卸载。

您需要在％preun中区分升级和删除。

我在* .spec文件中使用此模式：

%preun

if [ "$1" = "0" ]; then
    # package removal
    true; # bash doesn't like 'empty' conditional blocks
elif [ "$1" = "1" ]; then
    # package upgrade
    true; # bash doesn't like 'empty' conditional blocks
fi
