NAME

       gammu-smsd-run - documentation for RunOnReceive directive

DESCRIPTION

       Gammu  SMSD  can  be  configured  by RunOnReceive directive (see gammu-smsdrc for details) to run defined
       program after receiving every message. It can receive single message or more messages, which are parts of
       one multipart message.

       This parameter is executed through shell, so you might need to escape some special characters and you can
       include any number of parameters. Additionally parameters  with  identifiers  of  received  messages  are
       appended  to  the  command  line.  The  identifiers depend on used service backend, typically it is ID of
       inserted row for database backends or file name for file based backends.

       Gammu SMSD waits for the script to terminate. If you make some time consuming there, it  will  make  SMSD
       not  receive  new messages. However to limit breakage from this situation, the waiting time is limited to
       two minutes. After this time SMSD will continue in normal operation and might execute your script again.

       NOTE:
          All input and output file descriptors are closed when this program is invoked, so you have  to  ensure
          to open files on your own.

ENVIRONMENT

New in version 1.28.0.

Program is executed with environment which contains lot of information about the message. You can use it
together with NULL service (see gammu-smsd-null) to implement completely own processing of messages.

Global variables
SMS_MESSAGES
Number of physical messages received.

DECODED_PARTS
Number of decoded message parts.

PHONE_ID
New in version 1.38.2.

Value of PhoneID. Useful when running multiple instances (see smsd-multi).

Per message variables
The variables further described as SMS_1_... are generated for each physical message, where 1 is replaced
by current number of message.

SMS_1_CLASS
Class of message.

SMS_1_NUMBER
Sender number.

SMS_1_TEXT
Message text. Text is not available for 8-bit binary messages.

SMS_1_REFERENCE
New in version 1.38.5.

Message Reference. If delivery status received, this variable contains TPMR of original message

Per part variables
The variables further described as DECODED_1_... are generated for each message part, where 1 is replaced
by current number of part. Set are only those variables whose content is present in the message.

DECODED_1_TEXT
Decoded long message text.

DECODED_1_MMS_SENDER
Sender of MMS indication message.

DECODED_1_MMS_TITLE
title of MMS indication message.

DECODED_1_MMS_ADDRESS
Address (URL) of MMS from MMS indication message.

EXAMPLES

   Activating RunOnReceive
       To activate this feature you need to set RunOnReceive in the gammu-smsdrc.

          [smsd]
          RunOnReceive = /path/to/script.sh

   Processing messages from the files backend
       Following script (if used as RunOnReceive handler) passes message data to other program. This works  only
       with the gammu-smsd-files.

          #!/bin/sh
          INBOX=/path/to/smsd/inbox
          PROGRAM=/bin/cat
          for ID in "$@" ; do
              $PROGRAM < $INBOX/$ID
          done

   Invoking commands based on message text
       Following script (if used as RunOnReceive handler) executes given programs based on message text.

          #!/bin/sh

          # Check for sender number
          if [ "$SMS_1_NUMBER" != "+420123456789" ] ; then
              exit
          fi

          # Handle commands
          case "$SMS_1_TEXT" in
              "DMS A")
                  /usr/bin/dms-a
                  ;;
              "DMS B")
                  /usr/bin/dms-b
                  ;;
          esac

   Passing message text to program
       Following script (if used as RunOnReceive handler) passes message text and sender to external program.

          #!/bin/sh
          PROGRAM=/bin/echo
          for i in `seq $SMS_MESSAGES` ; do
              eval "$PROGRAM \"\${SMS_${i}_NUMBER}\" \"\${SMS_${i}_TEXT}\""
          done

   Passing MMS indication parameters to external program
       Following  script  (if  used  as  RunOnReceive  handler)  will  write information about each received MMS
       indication to the log file. Just replace echo command with your own program to do custom processing.

          #!/bin/sh
          if [ $DECODED_PARTS -eq 0 ] ; then
              # No decoded parts, nothing to process
              exit
          fi
          if [ "$DECODED_1_MMS_ADDRESS" ] ; then
              echo "$DECODED_1_MMS_ADDRESS" "$DECODED_1_MMS_SENDER" "$DECODED_1_MMS_TITLE" >> /tmp/smsd-mms.log
          fi

   Processing message text in Python
       Following script (if used as RunOnReceive handler) written in  Python  will  concatenate  all  text  from
       received message:

          #!/usr/bin/env python
          from __future__ import print_function
          import os
          import sys

          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 %s have sent text: %s' % (os.environ['SMS_1_NUMBER'], text))
