Linux的yum命令—

　　Yum（全称为 Yellow dog Updater, Modified）是一个在Fedora和RedHat以及CentOS中的Shell前端软件包管理器。基于RPM包管理，能够从指定的服务器自动下载RPM包并且安装，可以自动处理依赖性关系，并且一次安装所有依赖的软件包，无须繁琐地一次次下载、安装。

yum [options] [command] [package ...]

options：可选，选项包括-h（帮助），-y（当安装过程提示选择全部为"yes"），-q（不显示安装的过程）等等。
command：要进行的操作。
package操作的对象。

4.仅更新指定的软件命令：yum update <package_name>
5.列出所有可安裝的软件清单命令：yum list
6.删除软件包命令：yum remove <package_name>
7.查找软件包命令：yum search <keyword>
8.清除缓存命令:
- yum clean packages: 清除缓存目录下的软件包
- yum clean headers: 清除缓存目录下的 headers
- yum clean oldheaders: 清除缓存目录下旧的 headers
