Checking number of connections to Oracle using a shell

Question

I'm running Oracle 11g on Centos 5.5.

I want to know how many connections to Orcl DB by using shell script. In shell script: I think I will create many "connections" to DB and I will count them.

Example script:

#!/bin/bash
count=0
c=1
while [ $c -le 100 ]
do
sqlplus / as sysdba << EOF
exit;
EOF
        (( c++ ))
        ((count++))
done
echo "**************************************"
echo $count

Can you share me some ideas or solutions?
