详解linux中几个获取硬件详细信息的命令是

在Linux系统中，我们可以通过一些命令来获取硬件的详细信息，这些信息包括CPU、内存、硬盘、网络等，以下是几个常用的获取硬件详细信息的命令。

1、lscpu：这个命令可以显示关于CPU架构的信息，包括型号、核心数、线程数等，输入lscpu后，会显示如下信息：

2、free：这个命令可以显示系统的内存使用情况，输入free -h后，会显示如下信息：
   total        used        free      shared  buff/cache   available
   Mem:        7.7G        3.3G        987M        1.3G        3.5G        4.4G
   Swap:       2.0G        1.3G        677M
3、df：这个命令可以显示磁盘的使用情况，输入df -h后，会显示如下信息：
   Filesystem      Size  Used Avail Use% Mounted on
   /dev/sda1        50G   15G   34G   31% /
   tmpfs           7.9G     0  7.9G    0% /dev/shm
