一个简单的循环脚本问题

chunchun2012

测试环境为Redhat 4 U4,oracle 10.2.0.1
在/home/oracle下写了一个简单的脚本check.sh，内容如下
select to_char(sysdate,'HH24:MI:SS') now from dual;
select CPHBT from X$KCCCP where CPHBT>0;
!md5sum /u0/oracle/oradata/TESTwis/control01.ctl;
在sqlplus下运行正常
SQL> @check.sh

NOW
--------
16:19:42


     CPHBT
----------
809090683

ac99dc73241f11ad92cb415c61a9bb59  /u0/oracle/oradata/TESTwis/control01.ctl

为了多次运行这一脚本，想将其修改为循环结构，于是修改check.sh内容如下
declare
i number;
begin
for i in 1..20 loop
select to_char(sysdate,'HH24:MI:SS') now from dual;
select CPHBT from X$KCCCP where CPHBT>0;
!md5sum /u0/oracle/oradata/TESTwis/control01.ctl;
end loop;
end;
/

运行该脚本后出错，内容如下
SQL> @check.sh
!md5sum /u0/oracle/oradata/TESTwis/control01.ctl;
*

貌似循环结构下识别不了操作系统的命令？
那要想多次自动运行上述三个命令，请教一下，该如何操作？

非常感谢！学习了！

应该是在PL/SQL里面无法识别，所以报错。
用shell脚本应该是比较好的啦，简单写了下，可以参考下 :)

1. 
   
2. [oracle@stonedb stone]$ cat chk.sh
   
3. #!/bin/bash
   
4. 
   
5. for (( i=1; i<=10; i++ ))
   
6. do
   
7. echo "=== 第 $i 次检查 ==="
   
8. sqlplus -s '/ as sysdba' << EOL
   
9. select to_char(sysdate,'HH24:MI:SS') now from dual;
   
10. select CPHBT from X\$KCCCP where CPHBT>0;
    
11. host md5sum /u01/app/oracle/oradata/STONE11G/control01.ctl
    
12. EOL
    
13. done

“！”是sqlplus的命令，不是PL/SQL的命令，所以报错，用shell来实现循环就好了
