How to save commands into a file then run them again?

When I use sqlplus to organize a report, I have to write many commands, for example,

SQL> title center 'Test report';
SQL> column ename heading "Employee|name' format A8;
SQL> set pagesize 100;
SQL> set linesize 88;
SQL> select *

Is there any method to save all the commands into a file, then run the file? Do I have to type all the commands every time? I know I can save all the commands after "select *". But I do not know how to save the commands such as set, column etc.

Could anyone give me some help?

Your help will be very much appreciated?
