嵌入在 Bash 命令提示符中的 CPU 温度

Question

我想知道是否可以获取 CPU 温度并将其嵌入到命令提示符中。

这是我的输出sensors：

$}-sensors
coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +55.0°C  (high = +87.0°C, crit = +105.0°C)
Core 0:         +55.0°C  (high = +87.0°C, crit = +105.0°C)
Core 1:         +52.0°C  (high = +87.0°C, crit = +105.0°C)

你能告诉我如何使用该grep功能将温度嵌入到我的命令提示符中吗？

Answer 1

是的，这是可能的，但详细信息取决于您的系统。在大多数情况下，命令sensors应该显示它。

1. 安装必要的包

   sudo apt-get install lm-sensors
   

2. 运行sensors-detect并按照提示操作

   sudo sensors-detect
   

3. 如果sensors-detect告诉您安装任何额外的驱动程序。

4. 运行sensors以确保它有效

   $ sensors
   acpitz-virtual-0
   Adapter: Virtual device
   temp1:        +27.8°C  (crit = +110.0°C)
   temp2:        +29.8°C  (crit = +110.0°C)
   
   coretemp-isa-0000
   Adapter: ISA adapter
   Physical id 0:  +63.0°C  (high = +105.0°C, crit = +105.0°C)
   Core 0:         +62.0°C  (high = +105.0°C, crit = +105.0°C)
   Core 1:         +63.0°C  (high = +105.0°C, crit = +105.0°C)

5. 解析输出以仅获取 CPU 温度。

   正如您在上面看到的，我系统上的输出与您的不同。但是，我们在这里关心的那条线是一样的。您可以通过以下方式获取 CPU 温度：

   $ sensors | grep -oP 'Physical.*?\+\K[0-9.]+'
   63.0
   

6. 编辑您的~/.bashrc（或等效文件，如果您使用另一个 shell）并添加一个运行上述命令的函数：

   show_temp(){
       sensors | grep -oP 'Physical.*?\+\K[0-9.]+'
   }
   

7. 在提示中使用该函数。例如：

   PS1="\u@\h $(show_temp) $ "
