zero byte with String

My program would be creating a file, incase of non data from database it would only able to produce 'END, logically it would be file created by oracle in unix.

this file is showing zero byte but actully there are 4 char in file.This is not required, therefore what is command line should be written so that if the string matches then rm the file fromn location.

i have executed the commond based of zero byte but no luck.

NAME
radsqlrelay - relay SQL queries to a central database server SYNOPSIS
radsqlrelay [-?] [-d sql_driver] [-b database] [-f file] [-h host] [-u user] [-P port] [-p password] [-1] [-x] file_path DESCRIPTION
radsqlrelay tails a SQL logfile and forwards the queries to a database server. Used to replicate accounting records to one (central) data- base, even if the database has extended downtime. The SQL logfile is created by the rlm_sql_log module. The module must be configured in the radiusd server before you can use radsqlrelay. OPTIONS
-? Print usage help information. -d sql_driver Driver to use: mysql, pg, oracle. -b database Name of the database to use. -f file Read password from file, instead of command line. -h host Connect to host. -u user User for login. -P port Port number to use for connection. -p password Password to use when connecting to server. -1 One-shot mode: push the file to database and exit. -x Turn on debugging. file_path The pathname of the SQL logfile to use. NOTES
Oracle driver The command "radsqlrelay -d oracle -b db.domain.tld sql-relay" reads the database description stored in $TNS_ADMIN/tnsnames.ora: db.domain.tld = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = db.domain.tld)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = <DB SID>) ) ) SEE ALSO
