Bash 脚本用于获取 CPU 温度和 CPU 使用率并每秒将这些值保存到文件中

我需要在 Ubuntu 中编写脚本或命令行代码，从 lm_sensors 或类似程序获取 CPU 温度和 CPU 使用率百分比。我希望将这些信息保存到 .txt 文件中，并附上每次测量的日期和时间。我尝试编写下面的 .sh 文件。但它无法按我想要的方式工作。有人能帮我吗？

while true;
do
echo $( date '+%H:%M:%S' ): $( sensors | grep 'CPU Temperature' | sed -r 's/^.*:        +(.*)  +[(].*$/\1/' ) >> temperature.txt;
echo $( date '+%H:%M:%S' ): $( top -b -n 1 | grep 'CPU:') >> cpu.txt;
sleep 1; 
done

Sysfs 是解析内核子系统公开的属性的更好的来源。

echo "scale=1; $(sort -nr /sys/class/hwmon/hwmon1/{temp1_input,temp2_input,temp3_input} | head -n1) / 1000" | bc

输出：

38.0

# Temperature inputs.
TEMP_INPUT=$(echo /sys/class/hwmon/hwmon1/{temp1_input,temp2_input,temp3_input})

PREV_TOTAL=0
PREV_IDLE=0

while true; do
  # Get the total CPU statistics, discarding the 'cpu ' prefix.
  CPU=(`sed -n 's/^cpu\s//p' /proc/stat`)
  IDLE=${CPU[3]} # Just the idle CPU time.

  # Calculate the total CPU time.
  TOTAL=0
  for VALUE in "${CPU[@]}"; do
    let "TOTAL=$TOTAL+$VALUE"
  done

  # Calculate the CPU usage since we last checked.
  let "DIFF_IDLE=$IDLE-$PREV_IDLE"
  let "DIFF_TOTAL=$TOTAL-$PREV_TOTAL"
  let "DIFF_USAGE=(1000*($DIFF_TOTAL-$DIFF_IDLE)/$DIFF_TOTAL+5)/10"

  # Calculate highest CPU Temperature.
  HIGH_TEMP=$(echo "scale=1; $(sort -r $TEMP_INPUT | head -n1) / 1000" | bc)

  # Redirect CPU temperature and % of CPU usage to file.
  echo "$(date '+%H:%M:%S'): +${HIGH_TEMP}°C ${DIFF_USAGE}%" >> cpu.txt

  # Remember the total and idle CPU times for the next check.
  PREV_TOTAL="$TOTAL"
  PREV_IDLE="$IDLE"

  # Wait before checking again.
  sleep 1
done

输出cpu.txt：

12:02:27：+38.0°C 6%
