Linux下查看硬件：全面掌握系统硬件配置与性能 在Linux操作系统下，查看和管理硬件信息是一项至关重要的任务，无论是对于系统管理员、开发人员还是普通用户而言

    Linux以其强大的命令行工具和开源特性，提供了丰富的方法来获取详尽的硬件信息

    本文将详细介绍在Linux环境下，如何通过命令行工具和系统文件来查看和管理硬件信息，帮助你全面了解系统的硬件配置和性能

     一、概述 Linux系统提供了多种方法来查看硬件信息，包括使用命令行工具、查看系统文件以及利用图形化界面（如果安装了桌面环境）

    这些工具和方法各有优劣，但总的来说，命令行工具因其高效和兼容性而备受推崇

     二、使用命令行工具查看硬件信息 1.lscpu `lscpu`命令用于显示有关CPU架构的信息

    这个命令的输出非常详细，包括CPU型号、核心数、线程数、缓存大小、时钟速度等

     bash lscpu 输出示例： plaintext Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s):8 On-line CPU list list: 0-7 Thread(s) per core: 2 Core(s) per socket: 4 Socket(s):1 NUMAnode(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 158 Model name: Intel(R) Core(TM) i7-9700K CPU @ 3.60GHz Stepping: 12 CPU MHz: 1387.328 CPU max MHz: 4900.0000 CPU min MHz: 800.0000 BogoMIPS: 7200.00 Virtualization: VT-x L1d cache: 384K L1i cache: 384K L2 cache: 1.5M L3 cache: 12M NUMA node0CPU(s): 0-7 2.lshw `lshw`（List Hardware）是一个功能强大的工具，用于生成详细的硬件信息报告

    它可以以层次结构显示硬件信息，包括CPU、内存、主板、存储设备、网络接口等

     bash sudo lshw -short 输出示例（部分）： plaintext H/W path Device Class Description ==================================================== system Product Name(XYZ1234) /0 bus Motherboard /0/0 cpu processor Intel(R)Core(TM) i7-9700K CPU @ 3.60GHz /0/3a memory memory 16GiB System Memory /0/3b memory memory 16GiB System Memory /0/100 bridge bridge Intel Corporation 8th Gen Core Processor Host Bridge/DRAM Registers /0/100/1 bridge bridge Intel Corporation 8 Series/C220 Series Chipset Family PCI Express Root Port 1 /0/100/1.1 display display NVIDIA Corporation GP107【GeForce GTX 1050】 (rev a /0/100/14 usb bus xHCI Host Controller /0/100/14/1 usb device USB Receiver /0/100/14/2 usb device Kingston DataTraveler 3.0 /0/100/16 communication Ethernet controller Realtek Semiconductor Co., Ltd.

    它显示设备的挂载点、文件系统类型、大小等信息

     bash lsblk 输出示例： plaintext NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 232.9G 0 disk ├─sda1 8:1 0 1000M 0 part /boot/efi ├─sda2 8:2 0 1000M 0 part /boot └─sda3 8:3 0 230.9G 0 part / sdb 8:16 1 14.9G 0 disk └─sdb1 8:17 1 14.9G 0 part /mnt/data 4.free `free`命令用于显示系统的内存使用情况，包括物理内存、交换空间及其使用情况

     bash free -h 输出示例： plaintext total used free shared buff/cache available Mem: 15Gi 5.8Gi 2.3Gi 846Mi 6.9Gi 8.5Gi Swap: 2.0Gi 0B 2.0
