Network UPS Tools - UPS driver controller ${PACKAGE_VERSION}
Starts and stops UPS drivers via system service instances, see
the $ENUMERATOR
script for more details.
usage: $0 [OPTIONS] (start | stop | shutdown) [<ups>]
Options:
-h display this help
-t testing mode - prints actions without doing them
-D raise debugging level
start start all UPS drivers in ups.conf
start <ups> only start driver for UPS <ups>
stop stop all UPS drivers in ups.conf
stop <ups> only stop driver for UPS <ups>
Note: the "shutdown" options from original upsdrvctl are not currently
directly supported by this service management framework wrapper; instead
they are passed to the native upsdrvctl binary (your current user account
should have sufficient permissions to do that all):
shutdown shutdown all UPS drivers in ups.conf
shutdown <ups> only shutdown UPS <ups>
usage: $0 [OPTIONS] resync
resync call $ENUMERATOR
to update the mapping of service instances for
NUT drivers to device sections in 'ups.conf'
usage: $0 [OPTIONS] reconfigure
reconfigure call $ENUMERATOR
to remove and re-create the mapping of all service
instances for NUT drivers to device sections in
'ups.conf' e.g. after a NUT package upgrade
usage: $0 [OPTIONS] list [<ups>]
list call $ENUMERATOR
to list the mapping of service instances to device sections
list <ups> (optionally return the service instance name for one device)
usage: $0 [OPTIONS] show-config [<ups>]
show-config <ups> output config section from ups.conf for device <ups>
show-config ...or all devices if no <ups> argument was passed
