Centos repoquery—需要什么—已安装<；包装>；和百胜删除<；包装>；输出是不同的。如何获得相同的依赖项输出？

在执行yum-remove之前，如何检查将删除哪些依赖项？我刚发现两个包之间有些不同，所以请求您的帮助

JDK示例（执行yum时没有依赖项，但repoquery显示了依赖项-为什么会有差异？）

java gcj在这种情况下运行良好：

    root@server DEV # repoquery --whatrequires --installed java-1.5.0-gcj-1.5.0.0-29.1.el6.x86_64

我甚至尝试了

repoquery--whatrequires--installed--exactdeps

。这不会显示不正确的java gcj依赖项。

我发现解决方案列出的依赖项列表与

yum-remove

在删除之前列出的完全相同

因此，您可以采取适当的预删除操作，并了解将删除的内容

作为初学者，我已经在bash中编写了这篇文章，但它可以很容易地转换为木偶脚本、厨师食谱或任何自动化工具。主命令是

sudo-u-rpm-e--test

，它有两个保护门，以确保这是一个只读命令

打印完整依赖项列表的脚本：

#/bin/bash
级别=“1美元”
级别=`rpm-q$LEVEL`
如果[“$？”=“0”]
然后
全部=$LEVEL
时间：
做
OLD_DEP_COUNT=`echo$ALL | wc-w`
LEVEL=`sudo-u nobody rpm-e--test$LEVEL 2>&1 | grep-v'Failed dependencies'| awk-F'{print$NF}'| sed-es/[0-9]：//g`
ALL=“`echo”$LEVEL$ALL”| xargs-n1 | sort-u | xargs`”
NEW_DEP_COUNT=`echo$ALL | wc-w`
如果[“$OLD_DEP_COUNT”==“$NEW_DEP_COUNT”]
然后
因为我是以美元计算的；不要重复$i；完成
回显“依赖项的计数：”
echo$ALL | wc-w
打破
fi
完成
其他的
echo“找不到包”
fi

用法：

/script包\u名称
