cat /proc/cpuinfo
可以看到CPU是Intel® Core™ i7-10870H CPU @ 2.20GHz
16线程的
free
可以看到是分配了16298864KB的内存 也就是16G左右
使用top也可以查看
按Shift + E可以切换显示单位
RetHat系的可以使用，比如CentOS
cat /etc/redhat-release
这个命令在Ubuntu就失效了
Ubuntu可以使用
lsb_release -a 或者 cat /etc/issue
使用
cat /proc/version
使用lspci会列出全部的pci设备
通过grep过滤出网卡信息
lspci |grep -i 'eth'查看主板信息
dmidecode
这个命令会列出主板SMBIOS的各种详细信息，但虚机可能查看不了什么信息

暂时想到这么多，之后会继续补充
