Funny, mine's pretty similar:

#!/bin/sh
PORT=/dev/ttyS0
TARGET=~/projects/gpslogs
STAMP=`date --utc +%Y%m%dT%H%M`
echo Stamp $STAMP
echo Reading waypoints...
gpsbabel    -i garmin -f $PORT -o gpx -F "$TARGET/${STAMP}waypoint.gpx"
echo Reading tracklogs...
gpsbabel -t -i garmin -f $PORT -o gpx -F "$TARGET/${STAMP}tracklog.gpx"

This includes the hour and minute in the filename to deal with
multiple uploads in a day.  It also uses UTC rather than local
time which is a bit of over-engineering in this case, particularly
for somebody in the UK, but is consistent with the timestamps in
the GPX files and generally good practice for persistent data.
