EC20通过gammu接收短信再转发优化 前引在接收到短信之后会将内容较大的短信内容拆分到不同文件中保存，在之前的自动转发脚本转发短信文本内容不全解决最近在阅读gammu官方文档的时候发现官方有个Processing message text in Python 的示例：Following script (if used as RunOnReceive handler) written in Python will concatenate all text from received message:#!/usr/bin/env python import os numparts = int(os.environ["DECODED_PARTS"]) text = "" # Are there any decoded parts? if numparts == 0: text = os.environ["SMS_1_TEXT"] # Get all text parts else: for i in range(1, numparts + 1): varname = "DECODED_%d_TEXT" % i if varname in os.environ: text = text + os.environ[varname] # Do something with the text print("Number {} have sent text: {}".format(os.environ["SMS_1_NUMBER"], text))这个python脚本能将在不同文件中的短信内容拼接，刚好能够实现我们的需求，将这个python代码转写为shell代码，和之前的短信转发代码组合后的新代码：#!/bin/bash numparts=${DECODED_PARTS} text="" if [ "$numparts" -eq 0 ]; then text=${SMS_1_TEXT} else for i in $(seq 1 $numparts); do varname="DECODED_${i}_TEXT" if [ ! -z "${!varname}" ]; then text="${text}${!varname}" fi done fi echo "${text}" |mutt -s "树莓派转发${SMS_1_NUMBER}短信" mstzf@foxmail.com就能够完美实现短信转发功能gammu官网链接：{% link RunOnReceive,Gammu,https://docs.gammu.org/smsd/run.html#index-7 %}ec20模块使用：{% link 树莓派+EC20模块实现连接蜂窝网和短信收发,TeohZY,https://blog.teohzy.com/post/raspi-ec20/index.html %}
