MySQL: Delete Single table older than x days using Script

Notes for Self:

Following script can delete single table older than X days from the mysql DB. It was pretty useful for SYSLOG-NG loggin system, where table is daily created automagically in database using current date using YYYY_MM_DD format (dates have underscore sign). There are other solutions as well like creating procedure etc, but since this was older MySQL version , therefore I took this route.

#!/usr/bin/env bash
####!/bin/sh
#set -x
# Script to delete XX days older single table from particular DB
# Made for syslog-ng to save disk space

DEL_TABLE=`date +'%Y_%m_%d' -d "$DAYS day ago"`
logger syslog_ng script started $DATE , IT WILL DELETE $DEL_TABLE TABLE FROM $DB
# This is one time step.
echo " Script Started @ $DATE "
# --- Now Delete $DEL_TABLE TABLE from $DB table ...
$CMD "use $DB; SHOW TABLES;"
$CMD "use $DB; DROP TABLE $DEL_TABLE;"
DATE=`date +'%Y-%m-%d'`
logger TABLE_TRIMMING script ENDED $DATE , $DEL_TABLE TABLE FROM $DB deleted, confirm it plz
$CMD "use $DB; SHOW TABLES;"
echo "TABLE_TRIMMING  script ENDED at $DATE , $DEL_TABLE TABLE FROM $DB deleted, confirm it Please. Jz"
