linux shell實現自動獲取某地的天氣和空氣質量

因爲工作需要，實現了一個自動獲取某地天氣和空氣質量的shell程序。

#!/bin/bash

#This module using to get the weather of Henan, from webpage:http://www.weather.com.cn/html/province/henan.shtml


echo "Program starting..."

#############################################################

#以下是變量定義，定義省（拼音和中文），市（拼音和中文）

province='河南'

province_PY='henan'

city='鄭州'

city_PY='zhengzhou'


#############################################################

#以下是傳出的變量，可以直接使用

#weather_state 

#天氣質量


#temperature1

#最高天氣溫度


#temperature2

#最低天氣溫度


#city_air

#天氣質量


#city_pm25

#pm2.5指數


#city_aqi

#aqi指數

        echo " Getting the file from http://www.pm25.com//xx.html"


        air_url="www.pm25.com/"$city_PY.html

        echo "The city air is " $city_air



        city_pm25=$(sed -n '/全部監測點/p' city.air | awk -F '"' '{print $10}')

​
        echo "The city pm 2.5 figure is: " $city_pm25


        city_aqi=$(sed -n '/全部監測點/p' city.air | awk -F '"' '{print $8}')


        echo "The city's air AQI index is:" $city_aqi

這裏記錄下，也讓自己記住，在使用sed帶參數的時候要用’${parameter_name}’才能被sed解析。

下面又對程序進行了改良，使用函數方式進行調用

#GetWeatherAir函數說明：
#功能，傳入省市的信息，得到該城市的天氣和空氣參數
#1、參數說明
#   需要傳遞四個變量 省中文名稱 省拼音 市中文名稱 市拼音
#   調用示例 GetWeatherAir 河北 hebei 唐山 tangshan
#2、函數使用
#   默認函數中使用echo測試打印了取得的值（見註釋部分2），實際使用中可以註釋掉echo語句直接重定向輸出使用
