Bulk Convert your Dire Wolf logs to GPX

Dire Wolf won’t let you save both a daily and single log file of packets received, but if you log daily with LOGDIR, you can write a script that bundles up all the log files and then produces a GPX file of the output. This is useful if you want an idea of the area your digipeater or iGate is covering without trusting to aprs.fi or aprsdirect.com, which only provide the actual path taken and drop duplicate iGated packets.

Simple script for Linux:

#!/bin/bash
# merge log files
sed 1d *.log > log_merged.csv
# convert to gpx
log2gpx log_merged.csv > log_merged.gpx

(sed tip from Linux.com means you don’t need Python or similar)

Make it executable:

chmod +x merge_and_gpx.sh

Run or schedule in cron:

./merge_and_gpx.sh
