this shell script's quality is extremely poor

[borats]

Amazon AWS, please improve your bash quality.
Honestly, this script looks like someone cobbled it in couple of minutes. Worst yet, internal CR failed to review it with a careful set of eyes.

If this is your proposed diff it looks like this (LOGDIR instead of LOG_DIR) is a typo:

+[[ ! -d ${LOG_DIR} ]] && mkdir -p ${LOGDIR}

Happens to the best of us

Here

+[[ ! -d ${LOG_DIR} ]] && mkdir -p ${LOG_DIR}

Fixed. Last I counted, AWS had one of the largest devs in the world... and counting..
