如何准确检查yum中是否安装了软件包？

Question

我不断收到以下答案：

yum list installed | grep bind

或者

rpm -qa | grep bind

但这并不准确，因为我得到了一些其他像这样的绑定包的列表：

bind-utils-9.8.2-0.17.rc1.el6_4.5.x86_64
rpcbind-0.2.0-11.el6.x86_64
bind-libs-9.8.2-0.17.rc1.el6_4.5.x86_64
samba-winbind-3.6.9-151.el6.x86_64
samba-winbind-clients-3.6.9-151.el6.x86_64
ypbind-1.20.4-30.el6.x86_64

那不是我想要的。相反，我想准确检查是否已安装绑定核心包。例如。bind.x86_64 32:9.8.2-0.17.rc1.el6_4.6

我希望是这样的：

yum check installed bind

但希望有人可以照亮。

Answer 1

你试过这个吗？

$ yum list installed bind

Answer 2

发出此查询的方法要简单得多：rpm -qa | grep bind或rpm -q bind。如果您不完全确定包名称，则前者是最好的。

Answer 3

解析这个命令的结果是最完整的答案。您需要知道确切的包名称。

yum info bind
