grep only last occurred error in error.log,

hi folk i need your help to find one logic....

i have error log same as any other error logs which get populated by no of events and errors...

but i need to grep the last occured errors.. which cant be duplicate.

here is my script.
========================

Code:

#!/usr/bin/ksh
grep -i "STOP" $BATE/err.log > /tmp/bbs.lst   --capture error into tmp 
checkFile=/tmp/bbs.lst               
if [ -e $checkFile ]; then        ----if file is not empty 
mailx -s  'errors' XYZ@gmail.com < $checkFile
else
echo "dont worry process is fine" > /tmp/bbr.log   ---throwing into dump 
fi
rm -rf /tmp/bbs.lst       -----removing tmp

====================================

now problem is if i wake up this script every 2 min ,,
i need to check last 2 min errors which is in $BATE/err.log and sending to
/tmp/bbs.lst

suppose if it capture one error at 9:30 pm
after sometime if the script is wakup at 9:32 pm
and find again that same error which occured at 9:30 pm

so i want to capture the errors but dont want to duplicate it..

my err.log format will be something like this one

====================================================

Code:

2010-07-09 10:11:07  bb ERROR  250   XX.rm:  PROCESS STOP
2010-07-09 10:12:48  bb ERROR  250   XX.rm:  PROCESS STOP

save_binary_logs

SAVE_BINARY_LOGS(1p)					User Contributed Perl Documentation				      SAVE_BINARY_LOGS(1p)

NAME

       save_binary_logs - Concatenating binary or relay logs from the specified file/position to the end of the log. This command is automatically
       executed from MHA Manager on failover, and manual execution should not be needed normally.

SYNOPSIS

       # Test

       $ save_binary_logs --command=test  --binlog_dir=/var/lib/mysql --start_file=mysqld-bin.000002

       # Saving binary logs

       $ save_binary_logs --command=save --binlog_dir=/var/lib/mysql --start_file=mysqld-bin.000002 --start_pos=312
       --output_file=/var/tmp/aggregate.binlog

       # Saving relay logs

       $ save_binary_logs --command=save --start_file=mysqld-relay-bin.000002 --start_pos=312 --relay_log_info=/var/lib/mysql/relay-log.info
       --output_file=/var/tmp/aggregate.binlog

       save_binary_logs concatenates binary or relay logs from the specified log file/position to the end of the log. This tool is intended to be
       invoked from the master failover script(MHA Manager), and manual execution is normally not needed.

DESCRIPTION

       Suppose that master is crashed and the latest slave server has received binary logs up to mysqld-bin.000002:312. It is likely that master
       has more binary logs. If it is not sent to the slave, slaves will lose all binlogs from mysqld-bin.000002:312. The purpose of the
       save_binary_logs is to save binary logs that are not replicated to slaves. If master is reachable through SSH and binary logs are readable,
       saving binary logs is possible.

       Here is an example:

       $ save_binary_logs --command=save --start_file=mysqld-bin.000002 --start_pos=312 --output_file=/var/tmp/aggregate.binlog

       Then all binary logs starting from mysqld-bin.000002:312 are concatenated and stored into /var/tmp/aggregate.binlog. If you have binary
       logs up to mysqld-bin.000004, the following mysqlbinlog outputs are written.

       mysqld-bin.000002:Format Description Event(FDE), plus from 312 to the tail mysqld-bin.000003:from 0 to the tail, excluding FDE
       mysqld-bin.000004:from 0 to the tail, excluding FDE
