Exit status (2) from the manual page
Examples (4) from the manual page, untested
gpspipe -r -n 100
When gpsd is running, this example will send one hundred raw NMEA sentences to standard output, then exit:gpspipe -x 5 -w|sed -n '/TPV/{p;q}'
When gpsd is running, this example will wait at most 5 seconds for a TPV message, print it to stdout, then exit:socat EXEC:'gpspipe -r' TCP-LISTEN:2948,reuseaddr,fork
Use gpspipe and socat to serve NMEA from the local gpsd on tcp port 2948:socat EXEC:'gpspipe -rB' \
The paranoid may wish to have socat run as user 'nobody' and only accept connections from the local network.
