NAME

gpsdctl - tool for sending commands to gpsd over its control socket

SYNOPSIS

gpsdctl action device

NOTE

Eurolinux support for this package is limited. %{note2}

OPTIONS

action

may be add or remove. If no daemon instance is running when an add is requested, this program will launch one.

device

argument should be the pathname of a device. The device will be opened by gpsd to read sensor data.

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.

ENVIRONMENT

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

0

on success.

1

if the action was unknown or the write to the control socket failed,
