14 gpspipe is a tool to connect to gpsd and output the received sentences
15 to stdout. This makes the program useful as a pipe from gpsd to another
16 program or file.
17
18
19 gpspipe does not require root privileges, and can be run concurrently
20 with other tools connecting to the local gpsd without causing problems.
21
22
23 The output will consist of one or both of the raw NMEA or native gpsd
24 sentences. Each line can be optionally time stamped. There is also an
25 option to exit gracefully after a given count of packets.
26
27
28 Optionally a server, tcp port number and remote device can be given. If
29 omitted, gpspipe connects to 127.0.0.1 on the default port (2947) and
30 uses the first device opened by gpsd.
31
32
34 -h makes gpspipe print a usage message and exit.
35
36
37 -r causes raw NMEA sentences to be output.
38
39
40 -R causes super-raw (gps binary) data to be output. This overrides NMEA
41 and gpsd output modes.
42
43
44 -s option causes the collected data to be written to the specified se‐
45 rial device with setttings 4800 8N1. Thus gpspipe can be used with -s
46 and -r options to emulate a serial port hardwired to a GPS that gpsd is
47 managing.
48
49
50 -w causes native gpsdsentences to be output.
51
52
53 -t adds a timestamp to each sentence output.
54
55
56 -n [count] causes [count] sentences to be output. gpspipe will then ex‐
57 it gracefully.
58
59
60 -j makes the program send J=1 to the daemon, requesting fix hold across
61 cycles.
62
63
64 -v causes gpspipe to show a spinning activity indicator on stderr. This
65 is useful if stdout is redirected into a file or a pipe. By default the
66 spinner is advanced with every messages written; specifying -v more
67 than once will double the number of messages required to rotate the
68 spinner.
69
70
71 -V prints the version, then exits.
72
73
74 At least one of -R -r or -w must be specified.
75
76
78 When gpsd is running gpspipe -r -n 100 will send one hundred raw NMEA
79 sentences to standard output, then exit.
