Inxi：一个功能强大的获取 Linux 系统信息的命令行工具

Inxi 最初是为控制台和 IRC（网络中继聊天）开发的一个强大且优秀的命令行系统信息脚本。可以使用它获取用户的硬件和系统信息，它也用于调试或者社区技术支持工具。

使用 Inxi 可以很容易的获取所有的硬件信息：硬盘、声卡、显卡、网卡、CPU 和 RAM 等。同时也能够获取大量的操作系统信息，比如硬件驱动、Xorg 、桌面环境、内核、GCC 版本，进程，开机时间和内存等信息。

运行在命令行和 IRC 上的 Inxi 输出略有不同，IRC 上会有一些可供用户使用的默认过滤器和颜色选项。支持的 IRC 客户端有：BitchX、Gaim/Pidgin、ircII、Irssi、 Konversation、 Kopete、 KSirc、 KVIrc、 Weechat 和 Xchat 以及其它的一些客户端，它们具有展示内置或外部 Inxi 输出的能力。

在 Linux 系统上安装 Inxi

大多数主流 Linux 发行版的仓库中都有 Inxi ，包括大多数 BSD 系统。

1. $ sudo apt-get install inxi [On Debian/Ubuntu/Linux Mint]
2. $ sudo yum install inxi [On CentOs/RHEL/Fedora]
3. $ sudo dnf install inxi [On Fedora 22+]

在使用 Inxi 之前，用下面的命令查看 Inxi 所有依赖和推荐的应用，以及各种目录，并显示需要安装哪些包来支持给定的功能。

1. $ inxi --recommends
