Linux RMAN命令未在.sh文件中执行

我一直在尝试实现.sh文件，该文件打开RMAN promt并显示上次数据库备份的备份摘要

剧本

[apex@idmhost ~]$ cat b1.sh
ls
rman target / catalog rman/rman123@apexdb
list backup summary;

输出

sh b1.sh
0            db.rsp      Music            script_bkp.sh    Templates

正如您所看到的，它正在执行linux命令&同时连接到RMAN。但第三个并没有被处决。卡在哪里了
