How to hide sqlplus login/passwd

Dear all.

I need something like

$ sqlplus -s scott/tiger @script.sql

where script.sql is

BEGIN   ...

END;
/
EXIT I need this to compile PL/SQL packages under emacs. However, when sqlplus is running, everyone could do

$ ps -ef | grep sqlplus

and pick my password (tiger). How can I hide my password without need typing it every time I call sqlplus? Received on Fri Dec 11 1998 - 00:00:00 CST
