Ubuntu下查看CPU、内存和硬盘详细信息的几个命令

CPU:
型号:grep "model name" /proc/cpuinfo |awk -F ':' '{print $NF}'
数量:lscpu |grep "CPU socket" |awk '{print $NF}' 或 lscpu |grep "Socket" |awk '{print $NF}'
每个CPU的核数:lscpu |grep "Core(s) per socket" |awk '{print $NF}'

内存:
卡槽数量:sudo dmidecode -t memory |grep "Number Of Devices" |awk '{print $NF}'或sudo dmidecode -t memory |grep "Associated Memory Slots" |awk '{print $NF}'
内存数量:sudo dmidecode -t memory |grep -A16 "Memory Device$" |grep 'Size:.*MB' |wc -l
内存型号:
内存支持类型:sudo dmidecode -t memory |grep -A16 "Memory Device$" |grep "Type:"
每个内存频率:sudo dmidecode -t memory |grep -A16 "Memory Device$" |grep "Speed:"
每个内存大小:sudo dmidecode -t memory |grep -A16 "Memory Device$" |grep "Size:"
释放缓冲区内存:echo 3 > /proc/sys/vm/drop_caches

硬盘:
硬盘数量、大小:sudo fdisk -l |grep "Disk /dev/sd"
硬盘型号:sudo hdparm -i /dev/sda |grep "Model"

遇到根目录占满的情况:
查看磁盘文件系统与目录的占用情况:df -h
查看最近30天内出现的占用大小超10000 blocks的文件:find / -xdev -type f -mtime -30 -size +10000
