NAME
upsdrvctl - UPS driver controller
SYNOPSIS
upsdrvctl -h
upsdrvctl [OPTIONS] {start | stop | shutdown} [ups]
DESCRIPTION
upsdrvctl provides a uniform interface for controlling your UPS
drivers. You should use upsdrvctl instead of direct calls to the
drivers whenever possible.
When used properly, upsdrvctl lets you maintain identical startup
scripts across multiple systems with different UPS configurations.
OPTIONS
-h Display the help message.
-r directory
If starting a driver, this value will direct it to chroot(2)
into directory. This can be useful when securing systems.
This may be set in the ups.conf with "chroot" in the global
section.
-t Enable testing mode. This also enables debug mode. Testing
mode makes upsdrvctl display the actions it would execute
without actually doing them. Use this to test out your
configuration without actually doing anything to your UPS
drivers. This may be helpful when defining the 'sdorder'
directive in your ups.conf(5).
-u username
If starting a driver, this value will direct it to setuid(2) to
the user id associated with username.
If the driver is started as root without specifying this value,
it will use the username that was compiled into the binary.
This defaults to "nobody", and is far from ideal.
This may be set in ups.conf with "user" in the global section.
-D Raise the debug level. Use this multiple times for additional
details.
COMMANDS
upsdrvctl supports three commands - start, stop and shutdown. They
take an optional argument which is a UPS name from ups.conf(5).
Without that argument, they operate on every UPS that is currently
configured.
start Start the UPS driver(s).
stop Stop the UPS driver(s).
shutdown
Command the UPS driver(s) to run their shutdown sequence.
Drivers are stopped according to their sdorder value - see
ups.conf(5).
WARNING: this will probably power off your computers, so don't
play around with this option. Only use it when your systems are
prepared to lose power.
ENVIRONMENT VARIABLES
NUT_CONFPATH is the path name of the directory that contains ups.conf.
If this variable is not set, upsdrvctl and the driver use a built-in
default, which is often /usr/local/ups/etc.
DIAGNOSTICS
upsdrvctl will return a nonzero exit code if it encounters an error
while performing the desired operation. This will also happen if a
driver takes longer than the maxstartdelay period to enter the
background.
