我使用这样的命令：

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 Rpm和max 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/^.*: //"
