在Linux系统中，可以使用以下命令来检查设备的硬件信息：

检查CPU信息

 cat /proc/cpuinfo

该命令会输出CPU的详细信息，例如：

 processor   : 0
vendor_id   : GenuineIntel
cpu family  : 6
model       : 142

检查内存信息

cat /proc/meminfo
该命令会输出内存的详细信息，例如：

 # cxxu @ u20 in ~ [21:48:25]
$ cat /proc/meminfo
MemTotal:        1987684 kB

Cached:           766920 kB
SwapCached:          312 kB
...

检查硬盘信息

 sudo fdisk -l

该命令会输出硬盘的详细信息，例如：

 Disk /dev/sda: 238.47 GiB, 256060514304 bytes, 500118192 sectors
Disk model: KINGSTON SA400S3
