13 xgpsspeed -V
14
16 xgpsspeed is a speedometer that uses position information from gpsd.
17
18 The default display mode is a speed and track presentation modeled
19 after a marine navigation display; for backward compatibility the
20 --nautical option forces this mode. The --landspeed option produces a
21 simple speedometer.
22
23 The --speedunits option can be used to set the speed units for display;
24 follow the keyword with "knots" for nautical miles per hour, "kmh" for
25 kilometers per hour, or "mph" for miles per hour. The default is miles
26 per hour.
27
28 In the nautical mode only, --maxspeed sets the maximum on the
29 speedometer.
30
31 xgpsspeed will run fine as a normal user, and fine as root. Running
32 xgpsspeed under sudo will cause some loss of functionality.
33
35 -?, -h, --help
36 Causes the client to emit a summary of its options and then exit.
37
38 -device DEVICE
39 The device on the host to connect to. The default is empty (any).
40
41 -D LVL, --debug LVL
42 Sets the debug level, it is primarily for use by GPSD developers.
43 It enables various progress messages to standard error.
44
45 --host HOST
46 The host (server) to connect to. The default is localhost.
47
48 -p PORT, --port PORT
49 The port to connect to. The default is 2947.
50
51 -V, --version
52 This option causes each client to dump the package version and
53 exit.
54
56 By default, clients collect data from the local gpsd daemon running on
57 localhost, using the default GPSD port 2947. The optional argument to
58 any client may override this behavior: [server[:port[:device]]]

64 The environment variable GPSD_UNITS is checked if no unit system is
65 specified on the command line. It may be set to 'i'. 'imperial', 'm',
66 'metric', or 'n', 'nautical'.
67
68 LC_MEASUREMENT and then LANG are checked if no unit system has been
69 specified on the command line, or in GPSD_UNITS. If the value is 'C',
70 'POSIX', or begins with 'en_US' the unit system is set to imperial. The
71 default if no system has been selected defaults to metric.
