DESCRIPTION
cfengine is a language based system specifically designed for testing
and configuring unix-like systems attached to a TCP/IP network. You
can think of cfengine as a very high level language -- much higher
level than Perl or shell. A single statement can result in many
hundreds of links being created, or the permissions of many hundreds
of files being set. The idea of cfenginge is to create a single file
or set of configuration files which will describe the setup of every
host on your network.
cfagent runs on every host and parses one file (or file-set), the
configuration of the host is checked against this file and, if
desired, any deviations are fixed. cfagent reads a configuration file
called cfengine.conf in a directory pointed to by the environment
variable CFINPUTS. cfagent performs host integrity and security
checks as well as installing and repairing system configuration.
COMMAND LINE OPTIONS
-a (--sysadm) Print only the name of the system
administrator then quit.
-b (--force-net-copy) Forces net copy even if remote server is
localhost
-c (--no-check-files) Do not check access rights on file systems
-C (--no-check-mounts) Check mount points for consistency. If this
option is set then directories which lie in
the mount point area are checked to see
whether there is anything mounted on them.

Maintenance Commands
-d (--debug) Enable debugging output. (parsing -d1,run,
-d2, lite -d3)
-D (--define) Define a compound class symbol of the form
alpha.beta.gamma.
-e (--no-edits) Suppress file editing.
-E (--enforce-links) Globally force links to be created where
plain files or links already exist. You have
to use this in interactive mode and answer a
yes/no query before cfagent will run like
this.
-f (--file) Parse filename after this switch. By default
cfagent looks for a file called cfengine.conf
in the current directory.
-h (--help ) Help information. Display version banner and
options summary.
-H (--no-hard-classes) Prevents cfagent from generating any internal
class name information. Can be used for
emulation purposes.
-i (--no-ifconfig) Do not attempt to configure the local area
network interface.
-I (--inform) Switches on the inform output level, whereby
cfagent reports everything it changes..
-k (--no-copy) Do not copy/image any files.
-K (--no-lock) Ignore locks when running.
-l (--traverse-links) Normally cfagent does not follow symbolic
links when recursively parsing directories.
This option will force it to do so.
-L (--delete-stale-links)
Delete links which do not point to existing
files (except in user home directories, which
are not touched).
-m (--no-mount) Do not attempt to mount file systems or edit
the filesystem table.
-M (--no-modules) Ignore modules in actionsequence.
-n (--recon,--dry-run,--just-print)
No action. Only print what has to be done

Maintenance Commands
without actually doing it.
-N (--negate,--undefine) Cancel a set of classes, or undefine (set
value to false) a compound class of the form
alpha.beta.gamma.
-p (--parse-only) Parse file and then stop. Used for checking
the syntax of a program.
-q (--no-splay) Switch off host splaying (sleeping).
-s (--no-commands) Do not execute scripts or shell commands.
-S (--silent) Silence run time warnings.
-t (--no-tidy) Do not tidy file systems.
-u (--use-env) Causes cfagent to generate an environment
variable CFALLCLASSES which can be read by
child processes (scripts). This variable
contains a summary of all the currently
defined classes at any given time. This
option causes some system 5 systems to
generate a Bus Error or segmentation fault.
-U (--underscore-classes)
When this option is set, cfagent adds an
underscore to the beginning of all hard
system classes (like _sun4, _linux etc.) This
can be used to avoid naming conflicts if you
are so injudicious as to name a host by the
name of a hard class. Other classes are not
affected.
-v (--verbose) Verbose mode. Prints detailed information
about actions and state.
-V (--version) Print only the version string and then quit.
-x (--no-preconf) Do not execute the cf.preconf net
configuration file.
-X (--no-links) Do not execute the links section of a
program.
-w (--no-warn,--quiet) Do not print warning messages.
