shell得到一个字串，分割该字串循环处理

mornone

需求：有一个地址A，demo_com/ExportData/?action=json，返回结果是

1. 
   
2. ["demo_com\/ExportData\/Data\/20151013","demo_com\/ExportData\/Data\/20151014","demo_com\/ExportData\/Data\/20151012"]

，需要通过shell循环请求这个json串里的每个单独地址B，demo_com/ExportData/Data/20151013，这个同样返回一个json串，

1. 
   
2. ["demo_com\/ExportData\/Data\/20151013\/Data_6.txt","demo_com\/ExportData\/Data\/20151013\/Data_2.txt","demo_com\/ExportData\/Data\/20151013\/Data_4.txt","demo_com\/ExportData\/Data\/20151013\/Data_7.txt","demo_com\/ExportData\/Data\/20151013\/Data_8.txt","demo_com\/ExportData\/Data\/20151013\/Data_1.txt","demo_com\/ExportData\/Data\/20151013\/id","demo_com\/ExportData\/Data\/20151013\/Data_3.txt","demo_com\/ExportData\/Data\/20151013\/Data_5.txt","demo_com\/ExportData\/Data\/20151013\/Data_10.txt","demo_com\/ExportData\/Data\/20151013\/Data_9.txt"]

，现在的需求是使用shell如何实现自动下载B结果里所有的txt文件呢，从A返回的结果里得B地址，因此B的返回结果都不一样。
我是做php开发的，这在php里直接拿来循环数组就可以搞定，但是在shell下不知道使用什么来分割字串然后循环，在此感谢！

用|cut -d '","' -f 取到数组里？

1. list="demo_com\/ExportData\/Data\/20151013","demo_com\/ExportData\/Data\/20151014","demo_com\/ExportData\/Data\/20151012"
   
2. for uri in ${list//,/ }; do echo $uri; done

完整代码: 无法验证: 不知道使用wget回来的字符串是否就是 json 列表，没有其他字符
list=$(wget demo_com/ExportData/?action=json)
list=${list//[][]/}  #删除前后的 []
for uri in ${list//,/ }; do
    sublist=$(wget "$uri")
    sublist=${sublist//[][]/}  #删除前后的 []
    for addr in ${sublist//,/ }; do
        wget "$addr"
    done
done[/code]
