linux - Gammu runonreceive 不传递变量

Question

我想将我的 Rapsberry 配置为 SMS Ping Pong 播放器。所以我安装了 gammu-smsd 并配置了 gammu-smsdrc 如下:

# Configuration file for Gammu SMS Daemon

# Gammu library configuration, see gammurc(5)
[gammu]
# Please configure this!
port = /dev/ttyUSB3
pin= 4135
connection = at
# Debugging
logformat = textall

# SMSD configuration, see gammu-smsdrc(5)
[smsd]
RunOnReceive = sudo /var/spool/gammu/receivesms.sh
service = files
pin = 4135
# Increase for debugging information
debuglevel = 1
logfile = /var/spool/gammu/gammu.log
include_smsc = 491722270333

# Paths where messages are stored
inboxpath = /var/spool/gammu/inbox/
outboxpath = /var/spool/gammu/outbox/
sentsmspath = /var/spool/gammu/sent/
errorsmspath = /var/spool/gammu/error/

到目前为止，发送短信和接收短信工作正常!

所以我尝试了 runonreceive 的东西。并编写了一个小脚本来获取短信发件人号码和文本。如果文本是“ping”，gammu-smsd 应该将 pong 发送回发件人。

reveivesms.sh:

#!/bin/sh
from=$SMS_1_NUMBER
message=$SMS_1_TEXT
reply=""

if test "$message" = "Ping"; then
    reply="Pong!"
else
    reply="Y U NO PLAY PING PONG?"
fi


sudo echo "$reply" | /usr/bin/gammu-smsd-inject -c /etc/gammu-smsdrc TEXT "$from"

gammu.log 是:

嗯，没有消息回复...

所以我尝试不传递参数并将 receivesms.sh 更改为:

#!/bin/sh
sudo echo Gude Wie | /usr/bin/gammu-smsd-inject -c /etc/gammu-smsdrc TEXT 49160xxxx

一切正常。似乎传递给 receicesms.sh 的变量不起作用。但我不知道为什么？

Answer 1

使用 gammu-smsd-inject 运行接收以发送短信回复是一项任务。

对于遇到此问题的任何其他人。我通过将 gammu-smsd-inject 命令的 stdout 和 stderr 重定向到/dev/null 解决了这个问题。

echo "This somehow works" | gammu-smsd-inject TEXT $from > /dev/null 2>&1
