Inxi：一把获取 Linux 系统信息的军刀

June 21, 2019

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
```bash
$ 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。
```bash
$ inxi --recommends 
```
inxi将输出自检信息
```bash
inxi will now begin checking for the programs it needs to operate. First a check of the main languages and tools
inxi uses. Python is only for debugging data collection.

## 使用 Inxi 工具监控 Linux 系统
### 监控进程占用的 CPU 和内存资源
Inxi 默认显示 前 5 个最消耗 CPU 和内存的进程。 -t 选项和 c 选项一起使用查看前 5 个最消耗 CPU 资源的进程，查看最消耗内存的进程使用 -t 选项和 m 选项； -t选项 和 cm 选项一起使用显示前 5 个最消耗 CPU 和内存资源的进程。
