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。
大多数主流 Linux 发行版的仓库中都有 Inxi ，包括大多数 BSD 系统。部分系统已经默认安装有inxi
$ sudo apt-get install --no-install-recommends inxi [On Debian/Ubuntu/Linux Mint]
$ sudo yum install inxi [On CentOs/RHEL/Fedora]
$ 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。
$ inxi --recommends
inxi将输出自检信息
