Linux工具 2、ls_sensors 查看Linux CPU温度

Linux 下查看CPU温度的方法

1、安装

CentOS 系列
yum -y install lm_sensors
Ubuntu 系列
apt-get install lm_sensors

2、使用

> sensors --help
Usage: sensors [OPTION]... [CHIP]...
  -c, --config-file     Specify a config file #指定配置文件
  -h, --help            Display this help text 
  -s, --set             Execute `set' statements (root only) #只有root用户才可以执行set语句
  -f, --fahrenheit      Show temperatures in degrees fahrenheit #以华氏度显示温度
  -A, --no-adapter      Do not show adapter for each chip  #不显示每个芯片的适配器，不显示每个核心CPU的温度。
      --bus-list        Generate bus statements for sensors.conf #总线
  -u                    Raw output
  -v, --version         Display the program version

Use `-' after `-c' to read the config file from stdin. #使用-c从stin读取配置文件。
If no chips are specified, all chip info will be printed. #如果没有指定芯片，将打印所有芯片信息。打印每个核心CPU的温度。
Example chip names:
    lm78-i2c-0-2d   *-i2c-0-2d
    lm78-i2c-0-*    *-i2c-0-*
    lm78-i2c-*-2d   *-i2c-*-2d
    lm78-i2c-*-*    *-i2c-*-*
    lm78-isa-0290   *-isa-0290
    lm78-isa-*  *-isa-*
    lm78-*

4、小技巧

可以配合watch命令，以时间为间隔自动刷新当前CPU温度信息。

> watch -d -n 1 'sensors'
Every 1.0s: sensors                                                                                                                                     Sat Apr 13 01:58:59 2019
