Script to read file size and send email only if size > 0.

Hi Experts,
I have a script like
Code:
 
$ORACLE_HOME/bin/sqlplus username/password # << ENDSQL
set pagesize 0 trim on feedback off verify off echo off newp none timing off
set serveroutput on
set heading off
spool Schemaerrtmp.txt
select ' TIMESTAMP                     COMPUTER NAME                        ERROR TEXT ' from dual;
select to_char(error_time,'MM-DD-YYYY.HH.MI.SS') ||'  ;  ' || trim(computer_name) || '  ;  '||trim(error_code)|| ' ; '|| trim(rpad(error_text,30)) from  ta_error_log where rownum <=1000 and error_time > sysdate -1;
spool off
ENDSQL
dt=`date|awk '{print $1}'`
sed '1,5 d' Schemaerrtmp.txt > Schemaerr.txt
cat Schemaerr.txt |mailx -s " SPEAR Error Log file!!!! " $MAIL_LIST

This script sends a message even if "Schemaerr.txt" file is empty/zero bytes.
Need to modify the above script so that it send message only if "Schemaerr.txt" size is > 0 or non-empty.

Please advice.

Thanks
