问题描述
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。
这是我对 sensors 的输出：
$}-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)
您能否向我展示如何使用 grep 函数将温度嵌入到我的命令提示符中？
最佳答案
是的，这是可能的，但具体细节取决于您的系统。在大多数情况下，命令 sensors 应该会显示它。
-
安装必要的软件包
\n
sudo apt-get install lm-sensors\n -
运行
sensors-detect并按照提示操作\n
sudo sensors-detect\n -
如果
sensors-detect提示您安装任何额外的驱动程序。 -
运行
sensors以确保其正常工作\n

解析输出以仅获取 CPU 温度。
\n
如上所示，我的系统上的输出与您的不同。但是，我们在这里关心的行是相同的。您可以使用以下命令获取 CPU 温度：
\n
$ sensors | grep -oP 'Physical.*?\\+\\K[0-9.]+'\n63.0\n -
编辑您的
~/.bashrc(或等效文件，如果您使用的是其他 shell)并添加运行上述命令的函数：\n
show_temp(){\n sensors | grep -oP 'Physical.*?\\+\\K[0-9.]+'\n}\n -
在提示中使用该函数。例如：
\n
PS1="\\u@\\h $(show_temp) $ "\n
