+## Description and Usage
+# This file will take a sqlite3 dump sql file as input and convert it into Mysql dump file
+# sqlite3 latestCache.db .dump > latestCache_dump.sql will create latestCache_dump.sql from latestCache.db sqlite3 file
+# chmod +x sqlite_to_mysql.sh is needed on bash shell first to make this script run
+# ./sqlite_to_mysql.sh latestCache_dump.sql will produce latestCache_dump_mysql.sql which can be imported in MySQL
+
+# Check if input file is provided
