我正在尝试在我的服务器上设置一些基本的温度监控 -（不使用第三方工具）。
我已经在我的 Linux 机器上安装了几个库以使传感器在我的服务器上工作，现在我可以使用sensors可能返回如下数据的命令：
asb100-i2c-1-2d
Adapter: SMBus nForce2 adapter at 5500
in0: +1.79 V (min = +1.39 V, max = +2.08 V)
in1: +1.79 V (min = +1.39 V, max = +2.08 V)
in2: +3.34 V (min = +2.96 V, max = +3.63 V)
in3: +2.96 V (min = +2.67 V, max = +3.28 V)
in4: +3.06 V (min = +2.51 V, max = +3.79 V)
in5: +3.06 V (min = +0.00 V, max = +0.00 V)
in6: +3.04 V (min = +0.00 V, max = +0.00 V)
fan1: 6136 RPM (min = 2777 RPM, div = 2)
fan2: 0 RPM (min = 3534 RPM, div = 2)
fan3: 0 RPM (min = 10714 RPM, div = 2)
temp1: +37.0°C (high = +80.0°C, hyst = +75.0°C)
temp2: +26.5°C (high = +80.0°C, hyst = +75.0°C)
temp3: -0.5°C (high = +80.0°C, hyst = +75.0°C)
temp4: +25.0°C (high = +80.0°C, hyst = +75.0°C)
cpu0_vid: +1.750 V
w83l785ts-i2c-1-2e
Adapter: SMBus nForce2 adapter at 5500
temp1: +30.0°C (high = +85.0°C)
| grep temp然后我意识到我可以通过在命令末尾添加来轻松缩小范围，因此我尝试运行sensors | grep temp，并得到了以下结果：
temp1: +37.0°C (high = +80.0°C, hyst = +75.0°C)
temp2: +26.5°C (high = +80.0°C, hyst = +75.0°C)
temp3: -0.5°C (high = +80.0°C, hyst = +75.0°C)
temp4: +25.0°C (high = +80.0°C, hyst = +75.0°C)
temp1: +30.0°C (high = +85.0°C)
我意识到 temp3 显然没有正常运行，因此我修改了命令以消除该结果：sensors | grep temp[1,2,4]
temp1: +36.0°C (high = +80.0°C, hyst = +75.0°C)
temp2: +26.5°C (high = +80.0°C, hyst = +75.0°C)
temp4: +25.0°C (high = +80.0°C, hyst = +75.0°C)
temp1: +30.0°C (high = +85.0°C)
现在我想将其修剪掉，所以我所得到的只是一个逗号分隔的字符串，它可能看起来像这样。
+36.0,+26.5,+25.0,+30.0
然后我可以将其设置为每 5/10 分钟将数据提交到服务器一次。
我如何使用grep或其他命令来实现这一点？
答案1
使用awk：
sensors | awk '/temp[124]/ {sub("°C", "", $2); print($2)}'
或者用逗号分隔：
sensors | awk -v ORS=, '/temp[124]/ {sub("°C", "", $2); print($2)}' | sed 's/,$//'
