UPSDRVCTL(8)                      NUT Manual                      UPSDRVCTL(8)



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).

       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.
