Question

以下是rpm规范的第一个版本

    %post
    if [ "$1" = "1" ];
    then
        touch /usr/bin/item1.txt
        touch /usr/bin/item2.txt
        echo "i am in and this line is written from rpm 1-1">>/usr/bin/item1.txt
        echo "i am in and this line is written from rpm 1-1">>/usr/bin/item2.txt
    fi          
    %preun    
    if [ "$1" = "0" ];
    then
        sed -i "/i am in and this line is written from rpm 1-1 /d" /usr/bin/item1.txt
        sed -i "/i am in and this line is written from rpm 1-1 /d" /usr/bin/item2.txt
        rm -rf /usr/bin/item1.txt
        rm -rf /usr/bin/item2.txt
    fi
    if [ "$1" = "1" ];
    then
     # what should be here ?
    fi

rpm规范的最新版本如下

%post
if [ "$1" = "1" ];
then
    touch /usr/bin/item1.txt
    echo "xyz1" >> /usr/bin/item1.txt
    touch /usr/bin/item3.txt
    echo "xyz3" >> /usr/bin/item3.txt
fi

if [ "$1" = "2" ];
then
    # what should be here if i want to remove item2.txt file and add item3.txt
fi
%preun
if [ "$1" = "0" ];
then
# will i have to remove all the files item1 and item 2 along with item3.txt here 
fi

if [ "$1" = "1" ];
then
    ##
fi

我只想删除基本rpm的安装后脚本中已经安装的文件item2，并作为升级的一部分安装item3.txt文件。

似乎您对rpm打包的工作方式有错误的认识。以下是将创建package-1.0.0-0.spec和package-2.0.0-0.rpm文件的示例工作流程：

创建要打包的两个文件（这些命令发生在spec文件之外，就像您编写代码时一样）：

echo "i am in and this line is written from rpm 1" > item1.txt
echo "i am in and this line is written from rpm 1" > item2.txt

现在在这些部分旁边创建一个规范文件：

Version: 1.0.0
Release: 0

%install
install -d -m 0755 "${RPM_BUILD_ROOT}/usr/bin/"
cp item1.txt ${RPM_BUILD_ROOT}/usr/bin/
cp item2.txt ${RPM_BUILD_ROOT}/usr/bin/

%files
/usr/bin/item1.txt
/usr/bin/item2.txt

这将创建包含item1.txt和item2.txt的package-1.0.0-0.rpm 现在假设我们要创建下一个版本；然后：

echo "xyz1" >> item1.txt
echo "xyz3" >> item3.txt

规格文件现在应包含：

Version: 2.0.0
Release: 0

%install
install -d -m 0755 "${RPM_BUILD_ROOT}/usr/bin/"
cp item1.txt ${RPM_BUILD_ROOT}/usr/bin/
cp item3.txt ${RPM_BUILD_ROOT}/usr/bin/

%files
/usr/bin/item1.txt
/usr/bin/item3.txt

这将创建package-2.0.0-0.rpm。升级后，rpm现在将删除/usr/bin/item2.txt并安装新版本的item1.txt和item3.txt

如何删除在rpm后安装中安装的文件，而该文件在升级时不需要？
