dpkg是debian最早提出的一个软件包管理工具，因为早期并没有考虑到当下软件包之间这么复杂的依赖关系，所以并不能自动解决软件包的依赖问题，这个命令多用于安装本地的.deb软件包，也可以进行软件包的维护$sudo dpkg [-isLrP] [软件包或软件名]-i package安装一个软件包-s name查看软件包信息-L name查看软件包的安装路径-r name卸载软件，保留配置文件-P name卸载软件，同时删除配置文件

Description: VT102 terminal emulator for the X Window System
Rxvt is an 8-bit clean, color xterm replacement that uses significantly
less memory than a conventional xterm, mostly since it doesn't support
toolkit configurability or Tek graphics, but also since features can
be removed at compile-time to reflect your needs.
.
The distribution also includes rclock, the smaller/better xclock
replacement with appointment scheduling and xbiff functionality.
