gammu-smsd-run - documentation for RunOnReceive directive


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 charac‐ ters and you can include any number of parameters. Additionally parameters with identi‐ fiers 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.


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. SEE ALSO: faq-mms-download DECODED_1_MMS_SIZE Size of MMS as specified in MMS indication message.


Activating RunOnReceive To activate this feature you need to set RunOnReceive in the gammu-smsdrc. [smsd] RunOnReceive = /path/to/ 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 mes‐ sage 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/s ↲ msd-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(0, numparts): 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))
