如果我想在安装 RPM 软件包之前对其进行搜索，该怎么做？
如果我运行 yum info bind，它会给出基本概述：
[user@localhost ~]$ yum info bind

但是，有没有办法查询将通过 rpm 安装哪些依赖项和脚本？示例： rpm -q --scripts bind.x86_64 或 rpm -ql bind.x86_64
[user@localhost ~]$ rpm -ql bind.x86_64
package bind.x86_64 is not installed
答案1
人们可以用来yumdownloader戳一下包裹：
# yum -y install yum-utils
# yumdownloader bind
# rpm -qp --scripts bind*.rpm
为了避免安装yum-utils，另一个选择可能是：
# yum --downloadonly install bind
# find /var/cache/yum -name bind\*
如果您还需要检查这些依赖项，那么这样做的优点是可以降低依赖项。
