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 text.

       -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). In case of failure, further attempts may be executed by using
           the maxretry and retrydelay options - see ups.conf(5).

       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 upsd.conf and other
       configuration files. If this variable is not set, upsdrvctl 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.
