Could anyone please help?

I have written a small program that's actually working fine for me and extracting all the details I required. What code does is, it goes to all archivelog directories and see if archivelog backup was failed or successful

<<CODE>>

TMP_FILE='/ora/rman/scripts/tmp_chk.log'

chkbck ()
{
for i in `ls /ora/rman/logs/`;
do
        find /ora/rman/logs/$i/backup_a*.log -mtime -1 2>/dev/null
done
}

for i in `chkbck`;
do
       print $i | cut -d"_" -f3
        print $i | cut -d"/" -f6
        egrep -i 'Starting backup*' $i
        egrep -i 'Finished backup*' $i

if egrep -i 'exit status [^0]' $i
then
        print "Backup Failed"
else
        print "Backup Successful"
fi


done > $TMP_FILE
