通用方法(General Method)

查看CPU温度(Check CPU Temperature)

    root@linaro-alip:~# cat /sys/devices/virtual/thermal/thermal_zone0/temp   40000

    # 或者直接以度爲單位顯示 echo $[$(cat /sys/class/thermal/thermal_zone0/temp)/1000]° >>> 40°

查看CPU频率(Check CPU Frequency)

           cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq 
           >> 1200000
           cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq    
           >> 1800000
