NAME

SYNOPSIS

gpsdctl action device

OPTIONS

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

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.

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

on success.

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