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.

   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.

   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.

   DECODED_1_MMS_SIZE
          Size of MMS as specified in 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'])

      # Are there any decoded parts?
      if numparts == 0:
          print('No decoded parts!')
          sys.exit(1)

      # Get all text parts
      text = ''
      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))
