Bash命令提示符中嵌入的CPU温度

LinuxSailorTech

我想知道是否有可能获得CPU温度并将其嵌入命令提示符。

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)

您能告诉我如何使用该grep功能将温度嵌入到命令提示符中吗？

是的，可以，但是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。

安装必要的软件包
```
sudo apt-get install lm-sensors
```
运行sensors-detect并按照提示进行操作
```
sudo sensors-detect
```
如果提示sensors-detect您安装任何其他驱动程序。

运行sensors以确保其有效

解析输出以仅获取CPU温度。

如您在上面看到的，我系统上的输出与您的系统不同。但是，我们在这里关注的行是相同的。您可以通过以下方式获取CPU温度：
```
$ sensors | grep -oP 'Physical.*?\+\K[0-9.]+'
63.0
```
编辑您的~/.bashrc文件（如果使用其他外壳，则为等效文件），并添加一个运行上述命令的函数：
```
show_temp(){
    sensors | grep -oP 'Physical.*?\+\K[0-9.]+'
}
```
在提示中使用该功能。例如：
```
PS1="\u@\h $(show_temp) $ "
```
