树莓派-获取温度内存信息

脚本代码

#文件名:status.py  路径:~/
import os

#Get CPU temperature
def getCPUTemperature():
    with open("/sys/class/thermal/thermal_zone0/temp") as tempFile:
        return  str(float(tempFile.read())/1000)

#Get RAM status
def getRAMInfo():
    p = os.popen('free -m')
    i = 0
    while 1:
        i = i + 1
        line = p.readline()
        if i == 2:
            return(line.split()[1:4])
#温度
_temperature = getCPUTemperature()

#内存
RAM_stats = getRAMInfo()
RAM_total = RAM_stats[0]
RAM_used = RAM_stats[1] 
RAM_free  = RAM_stats[2] 

#字典
show_status_list = {'Temperature(C):' : _temperature, 'RAM Total(MB):':RAM_total, 'RAM Used(MB):':RAM_used, 'RAM Free(MB):':RAM_free}

if __name__ == '__main__':
    for k,v in show_status_list.items():
        print("{:18s}".format(k) + v) 

运行

python3 stayus.py

加入默认命令

sudo vim ~/.bashrc

在最后加上

alias status='python3 ~/status.py'

刷新下环境变量

source ~/.bashrc

效果

$ status
Temperature(C):   39.433
RAM Total(MB):    3776
RAM Used(MB):     127
RAM Free(MB):     3233
