【总结】

  • 系统硬件信息总览:dmidecode

    • CPU部分:dmidecode | grep CPU

    • 内存部分: 总容量=最大容 * 内存槽个数

      • 最大容量:dmidecode | grep “Maximum Capacity”

      • 内存槽个数:dmidecode | grep “Number Of Devices”

  • CPU

    • 完整信息:cat /proc/cpuinfo

    • 精简信息:cat /proc/cpuinfo | grep processor

  • 内存

    • 完整信息:cat /proc/meminfo

  • 硬盘:

    • 可用磁盘空间:df -h

    • 磁盘信息空间大小:fdisk -l | grep GB
