rpm -qip 查询未安装的包的信息 有问题
rpm -qi 包名 查询已安装的包的信息；
我已经安装了httpd的四个包：
[root@localhost Packages]# rpm -qa|grep httpd
httpd-tools-2.2.15-15.el6.centos.1.i686
httpd-manual-2.2.15-15.el6.centos.1.noarch
httpd-devel-2.2.15-15.el6.centos.1.i686
httpd-2.2.15-15.el6.centos.1.i686
-----------------------------------------------------------------------------------分隔符------------------
我使用rpm -qi httpd-tools 查询已安装的包 httpd-tools-2.2.15-15.el6.centos.1.i686的信息
[root@localhost Packages]# rpm -qi httpd-tools

既然httpd-tools-2.2.15-15.el6.centos.1.i686这个包已经是安装了的包，那么我用命令
rpm -qip httpd-tools-2.2.15-15.el6.centos.1.i686 查询光盘Packages目录下的这个包的信息，为什么显示没有安装此包？
[root@localhost Packages]# rpm -qip httpd-tools-2.2.15-15.el6.centos.1.i686.rpm

难道命令只能严格的通过包名与包全名来识别系统有没有安装软件包？
