GPSDCTL(8) GPSD Documentation GPSDCTL(8)NAMEgpsdctl - tool for sending commands to gpsd over its control socket
SYNOPSIS
gpdsctl action device
DESCRIPTION
This is a tool for sending an instance of gpsd commands over its
control socket to add or remove devices from the daemon's device list.
It is not intended to be called by users, but rather by the Linux
hotplug system and similar facilities.
The action argument may be "add" or "remove". If no daemon instance is
running when an add is requested, this program will launch one.
The "device" argument should be the pathname of a device. A device on
the list will be opened to read sensor data whenever a client requests
a watch.
Two environment variables are interpreted. GPSD_SOCKET sets the
location of the control socket. It defaults to /var/run/gpsd.sock if
the effective user ID of this program is root, /tmp/gpsd.sock
otherwise.
GPSD_OPTIONS may be a list of options to be passed to gpsd when this
tool launches it. It defaults to an empty string.
RETURN VALUES
1 if the action was unknown or the write to the control socket failed,
0 otherwise
