逻辑比较二，比较容易理解的实现

1. [root@localhost shell]# cat 123
   
2. "a":"1", "b":"2.3", "c":"1.235"
   
3. "a":"1.1","c":"1.23d","b":"2.32"
   
4. "b":"2.33", "c":"1.233","a":"1.2"
   
5. "b":"2.3f", "a":"1.3", "c":"1.23g"
   
6. "a":"1.4", "b":"2.3y", "c":"1.23h"
   
7. [root@localhost shell]# awk 'BEGIN{FS=","}{for(i=1;i<=NF;i++)id[substr($i,index($i,"\"")+1,1)]=substr($i,5+index($i,"\""),length($i)-5-index($i,"\""));print id["a"],id["b"],id["c"]}' 123
   
8. 1 2.3 1.235
   
9. 1.1 2.32 1.23d
   
10. 1.2 2.33 1.233
    
11. 1.3 2.3f 1.23g
    
12. 1.4 2.3y 1.23h

好蛋疼的空格和双引号，楼主的源文件真难受。。。
