gpsdctl(8)

NAME

   gpsdctl - 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
