10
12 This is a tool for sending an instance of gpsd commands over its
13 control socket to add or remove devices from the daemon's device list.
14 It is not intended to be called by users, but rather by the Linux
15 hotplug system and similar facilities.
16
17 The action argument may be "add" or "remove". If no daemon instance is
18 running when an add is requested, this program will launch one.
19
20 The "device" argument should be the pathname of a device. A device on
21 the list will be opened to read sensor data whenever a client requests
22 a watch.
23
24 Two environment variables are interpreted. GPSD_SOCKET sets the
25 location of the control socket. It defaults to /var/run/gpsd.sock if
26 the effective user ID of this program is root, /tmp/gpsd.sock
27 otherwise.
28
29 GPSD_OPTIONS may be a list of options to be passed to gpsd when this
30 tool launches it. It defaults to an empty string.
31
33 1 if the action was unknown or the write to the control socket failed,
