Network UPS Tools - UPS driver controller ${PACKAGE_VERSION}
|

|
Starts and stops UPS drivers via system service instances, see

the $ENUMERATOR
|

|
script for more details.

|

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

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

usage: $0 [OPTIONS] reconfigure

usage: $0 [OPTIONS] list [<ups>]

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>
|
