执行sql遇到一点小问题

执行 sqlplus **/**@** alter_table.sql >alter_table_exe.sql

得到alter_table_exe.sql如下:

我只想得到:
ALTER TABLE ACCOUNT MODIFY ( ACCOUNTNAME VARCHAR2(24));
ALTER TABLE ACCOUNT MODIFY ( BILLINGMONTH VARCHAR2(16));
ALTER TABLE ACCOUNT MODIFY ( CONTACTPERSON VARCHAR2(128));
ALTER TABLE ACCOUNT MODIFY ( RELATEDPHONE VARCHAR2(32));

那位大侠有好的办法,我想过用第三方语言,比如java来做;　　　　　　

不懂 跟 shell 有关系吗?　　　　　　

那这么老大的意见~~~~~~~~~;　　　　　　

言重了
