当我yum grouplist在Red Hat环境中运行时,我在" 可用组"列表下收到了以下组.

如何找出特定组中包含哪些包(例如"开发工具")？我想安装特定的软件包而不是整个组(特别是如果我不确定组中的内容).

$ yum grouplist

    Available Groups:
       DNS Name Server
       Development Tools
       Engineering and Scientific
       FTP Server
       Games and Entertainment
       Graphics
       Java Development
       KDE (K Desktop Environment)
       KDE Software Development
       MySQL Database
       News Server
       PostgreSQL Database
       Sound and Video
       Web Server
       Windows File Server

HashMaps allow for mapping key value pairs; what is the recommendation if there is an extra value?

i.e HashMap maps key-value pairs: Key, Value

What is the best way to map: Key, Value, Value1?

Thanks.
