The information about the binary log in MySQL can be found with the SHOW MASTER STATUS command:
mysql -uroot -p -e "SHOW MASTER STATUS\g"
the binary log names follow a base_name.nnnnnn convention, where nnnnnn represents a sequential file number. This number is increamented when the individual binary log raches the size as specified by max_binlog_size, the server is restarted, or the FLUSH [BINARY] LOGS statement is issued
