NAME

       cf-agent - evaluate CFEngine policy code and actuate change to the system.

SYNOPSIS

       cf-agent [OPTION]...  [FILE]

DESCRIPTION

       cf-agent evaluates policy code and makes changes to the system. Policy bundles are evaluated in the order
       of the provided bundlesequence (this is normally specified in the common control body). For each  bundle,
       cf-agent  groups promise statements according to their type. Promise types are then evaluated in a preset
       order to ensure fast system convergence to policy.

OPTIONS

       --bootstrap, -B
              Bootstrap CFEngine to the given policy server IP, hostname or :avahi (automatic detection)

       --bundlesequence, -b
              Set or override bundlesequence from command line

       --debug, -d
              Enable debugging output

       --define, -D
              Define a list of comma separated classes to be defined at the start of execution

       --self-diagnostics, -x
              Run checks to diagnose a CFEngine agent installation

       --dry-run, -n
              All talk and no action mode - make no changes, only inform of promises not kept

       --file, -f
              Specify an alternative input file than the default

       --help, -h
              Print the help message

       --inform, -I
              Print basic information about changes made to the system, i.e. promises repaired

       --negate, -N
              Define a list of comma separated classes to be undefined at the start of execution

       --no-lock, -K
              Ignore locking constraints during execution (ifelapsed/expireafter) if "too soon" to run

       --verbose, -v
              Output verbose information about the behaviour of the agent

       --version, -V
              Output the version of the software

       --legacy-output, -l
              Use legacy output format

       --color, -C
              Enable colorized output. Possible values: 'always',  'auto',  'never'.  If  option  is  used,  the
              default value is 'auto'

       --no-extensions, -E
              Disable extension loading (used while upgrading)

CFENGINE

       CFEngine   provides  automated  configuration  management  of  large-scale  computer  systems.  A  system
       administrator describes the desired state of a system using CFEngine policy code.  The  program  cf-agent
       reads  policy  code and attempts to bring the current system state to the desired state described. Policy
       code is downloaded by cf-agent from a cf-serverd daemon. The daemon cf-execd is responsible  for  running
       cf-agent periodically.
       Documentation for CFEngine is available at http://cfengine.com/documentation/.

PROMISE THEORY

       CFEngine  is built on principles from promise theory, proposed by Mark Burgess in 2004. Promise theory is
       a model of voluntary cooperation between individual,  autonomous  actors  or  agents  who  publish  their
       intentions  to one another in the form of promises. A promise is a declaration of intent whose purpose is
       to increase the recipient's certainty about a claim of past, present or future behaviour. For  a  promise
       to  increase  certainty,  the  recipient  needs to trust the promiser, but trust can also be built on the
       verification that previous promises have been kept,  thus  trust  plays  a  symbiotic  relationship  with
       promises.
