BASH I always rewrite

# prints stdout and logs to file 
function logger ()
{
	echo "${1}" | tee -a $LOG_FILE
}

# function to wrap errors and exit
# USAGE: rc=${PIPESTATUS[0]} ; check_return_value
rc=0
function check_return_value
{
	if [ $rc -eq 0 ] ; then
		logger "  ..... [INFO] Success! Return Value: $rc"
	else
		logger "  ..... [ERROR] Operation FAILED!!! Please check the logs!"
                exit 55
	fi
}
