How does your script looks like? Are you using a loop? Clarify your question.

You may use printf. I have also seen an awk counter like
Code:
awk '{while (1){printf "%s\r", ++a}}'

there are really many possible solutions. As Franklin said, it would be better if you posted your code here.

this will do i guess...
Code:
function ind {
while : ; do
printf "."
sleep 2
done
}
ind &
IND_PID=$!
mv /bin/more /bin/more1
/root/jre-6u16-linux-i586.bin << EOF &> /dev/null && mv /bin/more1 /bin/more;rm -f /root/jre-6u16-linux-i586.bin
yes
EOF
kill -9 $IND_PID
