你有在Linux下查看過CPU型號,內存大小,硬盤空間命令嗎?下面是學習啦小編跟大家分享的是Linux下查看CPU型號,內存大小,硬盤空間命令，歡迎大家來閱讀學習。
Linux下查看CPU型號,內存大小,硬盤空間命令
1 查看CPU
1.1 查看CPU個數
# cat /proc/cpuinfo | grep "physical id" | uniq | wc -l
2
**uniq命令：刪除重復行;wc –l命令：統計行數**
1.2 查看CPU核數
# cat /proc/cpuinfo | grep "cpu cores" | uniq
cpu cores : 4
1.3 查看CPU型號
# cat /proc/cpuinfo | grep 'model name' |uniq
model name : Intel(R) Xeon(R) CPU E5630 @ 2.53GHz
總結：該服務器有2個4核CPU，型號Intel(R) Xeon(R) CPU E5630 @ 2.53GHz
2 查看內存
2.1 查看內存總數
#cat /proc/meminfo | grep MemTotal
MemTotal: 32941268 kB //內存32G
2.2 查看內存條數
