exp 可以导出oracle 的数据库逻辑备份，但一般都是导出完成后再用压缩工具打包，有没有边导出连压缩的办法呢？有

下面就用exp\gzip实现

shell版本bash

在rhel 5下操作

SQL> conn test/test;
Connected.
SQL> select * from tab;

TNAME                                                        TABTYPE
———————————————————— ————–
CLUSTERID

TEST_TRAN                                                    TABLE

TEST_UNUSE                                                   TABLE

SQL> set linesize 200
SQL> run
1* select * from tab

———————————————————— ————– ———-
TEST_TRAN                                                    TABLE
