USAGE for ccheck.sh v1.0.2:

ccheck.sh [<SDPInstance>] [-p <Profile>] [-c <CfgFile>] [-y] [-v] [-d|-D]

or

ccheck.sh [-h|-man|-V]


DESCRIPTION:
	This script compares configurables set on the current server with best
	practices defined a data file.

OPTIONS:
 -p <Profile>
 	Specify a profile defined in the config file, such as 'demp' or 'prod'.  A profile
	defines a set of expected configurable values that can differ from the expected
	values in other profiles.  For example, for a demo environment, the filesys.P4ROOT.min
	might have an expected value of 128M, while the expected value in a prod (production)
	profile might be 5G.

	There is a default profile which always applies whether '-p' is specified or not.

	The profile specified with '-p' applies in addition to the default configuration.

 -c <CfgFile>
	Specify an alternate config file that defines best practice configurables. This
	is intended for testing.

 -L <log>
	Specify the path to a log file, or the special value 'off' to disable
	logging.  By default, all output (stdout and stderr) goes to
	$LOGS/ccheck.log

	NOTE: This script is self-logging.  That is, output displayed on the screen
	is simultaneously captured in the log file. Using redirection operators like
	'> log' or '2>&1' are unnecessary, nor is using 'tee'.

 -y	Live operation mode.  By default, any commands that affect data, such as
	setting configurables, are displayed, but not executed.  With the '-y' option,
	commands may be executed.

 -d	Display debug messages.

 -D     Set extreme debugging verbosity using bash 'set -x' mode. Implies -d.

 -si	Silient Mode.  No output is displayed to the terminal (except for usage errors
	on startup). Output is captured in the log.  The '-si' cannot be used with
	'-L off'.

HELP OPTIONS:
 -h	Display short help message
 -man	Display man-style help message

FILES:
	The standard configurables config file is:

	/p4/common/config/configurables.cfg

EXAMPLES:
	Example 1: Check configurables with the default profile, and no logging:

	ccheck.sh -L off

	Example 2: Check configurables with the 'prod' (Production) profile:

	ccheck.sh -p prod

	Example 3: Check configurables with the 'demo' profile, doing a verbose comparison:

	ccheck.sh -p demo -v

FUTURE ENHANCEMENTS:
	Presently, this ccheck.sh v1.0.2 only reports configurables. It does not
	support changing configurables.

	As the script is currently only capable of reporting, the '-y' option has no
	effect.

	Some possible future enhancements are:
	* Extend reporting to suggesting configuration changes.

	* Provide an option to make changes to configurables that are safe to change
	  immediately, and provide guidance on those configurables that are best set with
	  guidance and plannning.

	* Provide a way to specify custom exemptions for certain configurables.

	* Added multi-version support for backward compatibility. This version assumes
	  P4D 2023.1+ (though will be useful for older versions).
