       upsdrvctl - UPS driver controller


       upsdrvctl -h

       upsdrvctl [OPTIONS] {start | stop | shutdown} [ups]


       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.


       -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 sec-

       -t     Enable testing mode.  This also enables verbose  mode.   Testing
              mode  makes upsdrvctl display the actions it would execute with-
              out actually doing them.  Use this to test out  your  configura-
              tion  without actually doing anything to your UPS drivers.  This
              may be helpful when defining the  ’sdorder’  directive  in  your

       -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.

       -v     Enable verbose messages.


       upsdrvctl supports three commands - start,  stop  and  shutdown.   They
       take  an optional argument which is a UPS name from ups.conf(5).  With-
       out that argument, they operate on every UPS that is currently  config-

       start  Start the UPS driver(s).

       stop   Stop the UPS driver(s).

              Command  the  UPS  driver(s)  to  run  their  shutdown sequence.
              Drivers are stopped according  to  their  sdorder  value  -  see

              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.


       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.


       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 back-
