#
# Script to check deployment error dir for messages caused by oasis can reboot.
# Takes advantage of fact that when oasis3 controller boots it writes a message
# to the error log. The oasis procesing program 'extract' parses these messages
# to the deployment download directories for each deploymnet (eg: /oasis/m1/error) 
# 
# Will send email to list of users in set in the variable FAILMAIL below 
# Typically run as a cron job by user oasisa as part of the hourly processing
#
# Usage: check4restart m1 m2 m1test m2test
#
# SideFX: maintains a 'history' of restart messages for each mooring 
# in a hidden file indicated in the variable OLD (which is set/reset for
# each mooring instance below. (eg. /oasis/bin/.M1_Reset.list.
#
# Annoyances: if the 'history' file is missing (such as when the script
# is run for the first time on a deployment, the script will report
# a diff failure to stderr twice and send an email indicating a possible
# reset  has occured.  This may be a false alarm. Subsequent runs should
# proceed correctly unless someong deletes the history file or messes with
# the error dir for the deployment.
#
# The script can be tested by modifying any line in the history file.
# which will cause diff to trigger an email next time the script is run.
