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. If the effective
       user ID of this program is root then it usually defaults to
       /run/gpsd.sock, although some systems may use the deprecated
       /var/run/gpsd.sock instead. Non-root users will use /tmp/gpsd.sock.

       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
