# RSYNC bin between bluehost server & local Linux(TM))
# THIS SCRIPT PRESUMES OUR /usr/local/bin CONTENTS ARE *ALL* GOOD FOR OTHERS
# WHEN IN FACT WE MAY HAVE CONTENT TOXIC TO OTHER LINUX/POSIX/UNIX SYSTEMS.
# LIKEWISE WE TRUST THE REMOTE SYSTEM'S CONTENT TO BE GOOD FOR US.
# This is INSANITY UNLESS WE physically possess and control and administer,
# unless we MONITOR the LOG OF EACH SYNC to DETECT UPDATES TO OUR SYSTEM!
# "man rsync" will deliver the explanation of the options we default to.
#  My personal "take" was that I would "almost never" need an alternative.
#  Bluehost proves the exception with an rsync of incompatible compression,
#  which turns -auvzH into -auvH as option set.

# force		executable PERMISSIONS for scripts
 /usr/local/bin/executable	# script to normalize dir/file permissions

# BACKUP local	scripts library TO SERVER
rsync -auvH	/usr/local/bin	divservi@box6537.bluehost.com:~		\
				|& tee -a	/var/log/chronicle.log

# (notice we align vertically the same directory specs.)

# BACKUP server	scripts library TO LOCAL (BEWARE: TRUSTING REMOTE SERVER)
# we would prefer /usr/local/bin to appear last in our "${PATH}"
