rpm命令是RPM软件包的管理工具。rpm原本是Red Hat Linux发行版专门用来管理Linux各项套件的程序，由于它遵循GPL规则且功能强大方便，因而广受欢迎。逐渐受到其他发行版的采用。RPM套件管理方式的出现，让Linux易于安装，升级，间接提升了Linux的适用度。
常见用法：
用法: rpm [选项...]
-a：查询所有套件；
-b<完成阶段><套件档>+或-t <完成阶段><套件档>+：设置包装套件的完成阶段，并指定套件档的文件名称；
-c：只列出组态配置文件，本参数需配合"-l"参数使用；
-d：只列出文本文件，本参数需配合"-l"参数使用；
-e<套件档>或--erase<套件档>：删除指定的套件；
-f<文件>+：查询拥有指定文件的套件；
-h或--hash：套件安装时列出标记；
-i：显示套件的相关信息；
-i<套件档>或--install<套件档>：安装指定的套件档；
-l：显示套件的文件列表；
-p<套件档>+：查询指定的RPM套件档；
-q：使用询问模式，当遇到任何问题时，rpm指令会先询问用户；
-R：显示套件的关联性信息；
-s：显示文件状态，本参数需配合"-l"参数使用；
-U<套件档>或--upgrade<套件档>：升级指定的套件档；
-v：显示指令执行过程；
-vv：详细显示指令执行过程，便于排错。
