or

DESCRIPTION:
	This script manages Docker environment for the Helix Installer Test Suite.

	The test_hi.sh runs the actual tests within VMs managed by this script.

OPTIONS:
 -b	Build Docker images, and then stop before running tests. By default,
 	tests are executed after images are built.

 -f	Specify '-f' to force a rebuild of the Docker image by passing '--no-cache'
 	option to the 'podman build' command.

 -p	Specify '-p' to pull the latest Docker source image by passing '--pull'
 	option to the 'podman build' command.

 -B	Specify '-B' as a shorthand for '-b -f -p'.

 -o	Specify a comma-delimited list of operating systems to build.
 	Valid operating system values are:

	rocky8 rocky9 centos7 ubuntu20 ubuntu22

 -hb <helix_installer_branch>
 	Specify the Helix Installer branch to test.  The default is dev.

 -sb <sdp_branch>
 	Specify the SDP branch to test.  The default is main, which always
	represents the latest version officially released for general
	availability.

 -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

	hits.<DateTimeStamp>.log

	NOTE: This script is self-logging.  That is, output displayed on the
	screen is simultaneously captured in the log file.  Do not run this
	script with redirection operators like '> log' or '2>&1', and do not
	use 'tee'.

 -si	Operate silently.  All output (stdout and stderr) is redirected to the
 	log only; no output appears on the terminal.  This cannot be used with
	'-L off'.
      
	This is useful when running from cron, as it prevents automatic email
	from being sent by cron directly, as cron does when a script called
	from cron generates any output.  This script is then responsible for
	email handling, if any is to be done.

 -n	No-Op.  Prints podman, rsync, and other commands instead of running
 	them.

 -D     Set extreme debugging verbosity.

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

EXAMPLES:
	Example 1: Normal test run on all platforms - no arguments.
	hits.sh

	Example 2: Test image build only
	hits.sh -B

	Example 3: Test on a single platform:
	hits.sh -o centos7

	Example 4: See podman and other commands without executing them.
	hits.sh -n
