SQL * plus automatically runs glogin. SQL, which contains the global default settings. You can customize your SQL * plus environment as needed.

1) First, define an environment variable sqlpath in the system environment settings, and set your own environment scripts login. SQL and connect. SQL.
Put them in the SQLPATH directory.

2) define a login. SQL script, which is automatically executed when SQL * PLUS is enabled.

Exercise:
Scripts think. SQL and sub_think. SQL are available under $ Oracle_HOME/dbs.
Think. The content of SQL is: @ sub_think. SQL
Then we can execute:
@ $ ORACLE_HOME/dbs/think. SQL
2) edit the current input.
Edit
Generally, the DML, DDL, and DCL statements are SQL * plus statements. After execution, they are saved in the memory area of the SQL buffer, and only one recently executed SQL statement can be saved.
3) re-run the statement in SQL buffer
/
4) output the displayed content to the specified file
Spool filename
/* Anything you do in SQL * plus */
Spool off
Then you can view it in the file path.
