OPTIONS

   Help Options:
       -h, --help
              Show help options

       --help-all
              Show all help options

       --help-output
              Show output help

       --help-required
              Show required arguments

       --help-command
              Show command options (mutually exclusive)

       --help-additional
              Show additional options

   Output Options:
       --output-as=FORMAT
              Specify output format as one of: text (default), xml

       --output-to=DEST
              Specify file name for output (or "-" for stdout)

   Required Arguments:
       -n, --name=NAME
              The attribute's name

       -P, --pattern=PATTERN
              Operate on all attributes matching this pattern (with -B, -D, -U, or -Y)

   Command:
       -U, --update=VALUE
              Update   attribute's  value.  Required:  -n/--name  or  -P/--pattern.   Optional:  -d/--delay  (if
              specified, the delay will be used if the attribute  needs  to  be  created,  but  ignored  if  the
              attribute already exists), -s/--set, -p/--private, -W/--wait, -z/--utilization.

       -B, --update-both=VALUE
              Update  attribute's  value  and time to wait (dampening) in the attribute manager. If this changes
              the value or dampening, the attribute will also be written to the  cluster  configuration,  so  be
              aware that repeatedly changing the dampening reduces its effectiveness.  Requires -d/--delay

       -Y, --update-delay
              Update  attribute's  dampening  in  the  attribute  manager.  If  this  changes the dampening, the
              attribute will also be written to the cluster configuration, so be aware that repeatedly  changing
              the dampening reduces its effectiveness.  Requires -d/--delay

       -Q, --query
              Query  the  attribute's  value from the attribute manager. By default this will query the value of
              the attribute on the local node.  Use -N/--node for the value on a given node, or -A/--all for the
              value on all nodes.

       -D, --delete
              Unset attribute from the attribute manager. At the moment, there is no way to remove an attribute.
              This option will instead set its value to the empty string.

       -R, --refresh
              (Advanced) Force the attribute manager to resend all current values to the CIB

   Additional Options:
       -d, --delay=SECONDS
              The time to wait (dampening) in seconds for further changes before sending to the CIB

       -s, --set=SET
              (Advanced) The attribute set in which to place the value

       -N, --node=NODE
              Use the named node for setting and querying the attribute (instead of the local one)

       -A, --all
              Show values of the attribute for all nodes (query only)

       -l, --lifetime=SECTION
              (Not yet implemented) Lifetime of the node attribute (silently ignored by cluster)

       -p, --private
              If this creates a new attribute, never write the attribute to CIB

       -W, --wait=UNTIL
              Wait for some event to occur before returning.  Values are  'no'  (wait  only  for  the  attribute
              daemon to acknowledge the request), 'local' (wait until the change has propagated to where a local
              query  will  return  the  request  value, or the value set by a later request), or 'cluster' (wait
              until the change has propagated to where a query anywhere on the cluster will return the requested
              value, or the value set by a later request).  Default is 'no'.

       -z, --utilization
              When creating a new attribute, create it as a node utilization attribute instead  of  an  instance
              attribute.   If the attribute already exists, its existing type (utilization vs. instance) will be
              used regardless.  (with -B, -U, -Y)

   Application Options:
       -$, --version
              Display software version and exit

       -V, --verbose
              Increase debug output (may be specified multiple times)
