【Shell】Display the ddl for all users in Oracle DB with bash script

脚本说明：

1、普遍用于 使用expdp/impdp 数据泵进行的数据(全库或者特定schemas)迁移

2、适用于无PDB的Oracle环境

3、适用于RAC,SI,ADG 以及多实例的环境

使用方法：

创建脚本为 display_all_users_ddl.sh 然后将正文内容贴入 并保存，然后执行 bash display_all_users_ddl.sh , 

若环境为多实例，那么可以显示的数字或者实例名即可，最终在当前目录会生成四个.log结尾的文件
