如何获取/proc/cpuinfo中的某些单词

如何获取/proc/cpuinfo中的某些单词

我使用这样的命令:

test@localhost:~> cat /proc/cpuinfo

例如,如果我想获取字段的值cpu MHz,那么我会写...并得到...

使用哪个脚本。这是另一个例子:

test@localhost:~> sensors

amdgpu-pci-0800
Adapter: PCI adapter
vddgfx:       +0.84 V  
fan1:         839 RPM  (min =    0 RPM, max = 3200 RPM)
edge:         +43.0°C  (crit = +94.0°C, hyst = -273.1°C)
power1:       39.05 W  (cap = 175.00 W)

k10temp-pci-00c3
Adapter: PCI adapter
Vcore:        +0.92 V  
Vsoc:         +1.08 V  
Tdie:         +46.2°C  
Tctl:         +46.2°C  
Icore:       +14.00 A  
Isoc:         +9.75 A  

如何准确得到min Rpmmax Rpm

答案1

grep例如,使用grep "cpu MHz" /proc/cpuinfo来选择线路。用于sed从行中提取一些文本,例如删除冒号之前的所有内容。将它们与管道 ( |) 结合起来即可完成这两项操作。

grep "cpu MHz" /proc/cpuinfo | sed -e "s/^.*: //"
