问题： 1、shell 连接数据库操作
dbtools.sh 数据库名 用户名 密码 操作语句 输出文件 操作日志
例: dbtools.sh "CHNDB1" "dbchnadm" "dbpwd" "select rownum as rn from dual connect by rownum<=3" "myfile.txt" "mydb.log"
作用：连接数据库执行语句，执行结果生成文件myfile.txt
myfile.txt 文件内容:
1
2
3
----------源码--------------
#!/bin/sh
username=$1
pwd=$2
database=$3
sql=$4
outputfile=$5
