       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

       -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


       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

       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
