著色感測器的輸出

我sensors過去常常關注控制台上的 CPU 溫度。這是輸出的一部分：

coretemp-isa-0001
Adapter: ISA adapter
Physical id 1:  +45.0°C  (high = +80.0°C, crit = +90.0°C)
Core 0:         +39.0°C  (high = +80.0°C, crit = +90.0°C)
Core 1:         +39.0°C  (high = +80.0°C, crit = +90.0°C)
Core 2:         +40.0°C  (high = +80.0°C, crit = +90.0°C)
Core 3:         +38.0°C  (high = +80.0°C, crit = +90.0°C)
Core 4:         +40.0°C  (high = +80.0°C, crit = +90.0°C)
Core 8:         +39.0°C  (high = +80.0°C, crit = +90.0°C)
Core 9:         +38.0°C  (high = +80.0°C, crit = +90.0°C)
Core 10:        +38.0°C  (high = +80.0°C, crit = +90.0°C)
Core 11:        +39.0°C  (high = +80.0°C, crit = +90.0°C)
Core 12:        +39.0°C  (high = +80.0°C, crit = +90.0°C)

nouveau-pci-0200
Adapter: PCI adapter
GPU core:     +0.92 V  (min =  +0.92 V, max =  +1.00 V)
fan1:        2220 RPM
temp1:        +48.0°C  (high = +95.0°C, hyst =  +3.0°C)
                      (crit = +105.0°C, hyst =  +5.0°C)
                      (emerg = +135.0°C, hyst =  +5.0°C)

我想“著色”這個輸出。特別是，如果溫度高於某個門檻值，我希望它們以紅色顯示。因此，例如，假設門檻值為 60，那麼+60.0°C, +61.0°C,+62.0°C等的任何出現都應該是紅色的（理想情況下，我想要一個基於兩個不同門檻值的橙色級別和一個紅色級別，但是一個一級解決方案也會很棒）。理想情況下，這也應該與watch sensors.

用法： sensors | ./color_sensors.awk

手錶用法： watch -c 'sensors | ./color_sensors.awk'

#!/usr/bin/awk -f

BEGIN {
   DEFAULT_COLOR = "\033[;m";
   RED           = "\033[1;31m";
   MAGENTA       = "\033[1;35m";

   # CPU_thresholds
   cpu_high = 60; 
   cpu_middle = 50; 

   # GPU_thresholds
   gpu_high = 80; 
   gpu_middle = 70; 
}

function colorize(temp, mid_trsh, high_trsh) {
   new_color = "";  

   temp_number = temp;
   gsub("[^0-9]","",temp_number);
   gsub(".$","",temp_number);

   if(temp_number >= high_trsh) 
       new_color = RED;
   else if (temp_number >= mid_trsh) 
       new_color = MAGENTA;

   return new_color temp DEFAULT_COLOR;
}

/Core/          { $3 = "\t" colorize($3, cpu_middle, cpu_high); }
/Physical id/   { $4 = "\t" colorize($4, cpu_middle, cpu_high); }
# Multiple spaces added for alignment here - "\t      ".
/temp1/         { $2 = "\t      " colorize($2, gpu_middle, gpu_high) " "; }
               { print; }

結果：
