最近看邮件列表看见有用户使用inxi命令来显示自己的系统信息，看起来很好用。我试了一下，在 ubuntu 上可以直接用apt安装。根据其 man 手册，的确利于用户使用：
inxi is a command line system information script built for for console and IRC. It is also used for forum technical support, as a debugging tool, to quickly ascertain user system configuration and hardware. inxi shows system hardware, CPU, drivers, Xorg, Desktop, Kernel, GCC ver‐ sion(s), Processes, RAM usage, and a wide variety of other useful infor‐ mation.
我使用inxi -F查看了几台机器的信息：
