用awk处理数据文件，卸出数据块中的数据
卸出指定块的数据：./getSegData.sh [DATAFILE] [BLOCK_ID] [BLOCK_SIZE]
根据给定的段头卸出该段的数据：./UnloadDataBySegHeader.sh [DATAFILE] [BLOCK_ID] [BLOCK_SIZE]

示例：（卸出file$表的数据）
 [root@zhangqiaoc odu]# ./UnloadDataBySegHeader.sh /oradata/SOURCE10/system01.dbf 113 8192

不能处理中文，现在处理字符是通过定义的CHARR数组来进行，对字符类型的判断，也是简单的限定于单个字符的范围来处理，该处理方法是错误的
正确的处理方法应该如下，英文也是
[root@zhangqiaoc odu]# echo "206 210 49 97 101 119 195 199 176 174 196 227 108 111 118 101 50 50 50" |awk '{
>   printf "%c",$1
>   printf "%c",$2
>   printf "%c",$3
>   printf "%c",$4
>   printf "%c",$5
>   printf "%c",$6
>   printf "%c",$7
>   printf "%c",$8
>   printf "%c",$9
>   printf "%c",$10
>   printf "%c",$11
>   printf "%c",$12
>   printf "%c",$13
>   printf "%c",$14
>   printf "%c",$15
>   printf "%c",$16
>   printf "%c",$17
>   printf "%c",$18
>   printf "%c",$19
>   printf "\n"  
> }'

只能对普通的堆栈表，只包含数字，日期，英文字符来处理

卸出数据字典file$中无数据文件名称，自动完成卸出TRUNCATE了的数据不好弄。

写的很乱，学习目的。实际使用用熊哥的ODU很好很强大
