Hide SqlPlus username/password in UNIX Script

I want to hide the username and password when I run SqlPlus on in a UNIX script. How do I do this?

My original solution was to
I execute the script under a super user (root user), which has no password, but the

Example of what I have so far ...
 echo "execute sample;" | $ORACLE_HOME/bin/sqlplus scott/tiger

 Step 1: I login to UNIX using scott/tiger for username/password
 Step 2: I change to the Super User (ie. su superuser), which has no password
 Step 3: Run the script with following line ...
           echo "execute sample;" | $ORACLE_HOME/bin/sqlplus superuser/
         I tried changing the username/password to the superuser.

Of course, this failed. My reason for Step 3, was since superuser had no password associated with it, it would automatically login.

Thanks!
