最近在写一个模仿 dropbox_uploader 的百度网盘的shell脚本。通过调用pcs的api返回一个目录下的所有文件。返回的json数据如下：

 {"list":[{"fs_id":1878243434,"path":"\/apps\/zjhui\/test","ctime":1392866001,"mtime":1392866001,"md5":"","size":0,"isdir":1},{"fs_id":3901347206,"path":"\/apps\/zjhui\/upload","ctime":1392860719,"mtime":1392860719,"md5":"","size":0,"isdir":1},{"fs_id":3190602252,"path":"\/apps\/zjhui\/aaaaaaaa","ctime":1392885465,"mtime":1392885465,"md5":"783b7e40cdfb4a1344d15b1f7081af66","size":35121,"isdir":0},{"fs_id":3734744594,"path":"\/apps\/zjhui\/baidu-pcs.txt","ctime":1390898949,"mtime":1390898949,"md5":"5ccce0498cf29996399750789f415bb8","size":450,"isdir":0},{"fs_id":4176732013,"path":"\/apps\/zjhui\/bash","ctime":1389845838,"mtime":1389845838,"md5":"286dc423e71186936c39e3507d2d0cf1","size":2076,"isdir":0},{"fs_id":1122970857,"path":"\/apps\/zjhui\/LICENSE","ctime":1391567032,"mtime":1391567032,"md5":"783b7e40cdfb4a1344d15b1f7081af66","size":35121,"isdir":0},{"fs_id":3086666598,"path":"\/apps\/zjhui\/LICENSE-0205","ctime":1391569592,"mtime":1391569592,"md5":"783b7e40cdfb4a1344d15b1f7081af66","size":35121,"isdir":0},{"fs_id":4120839796,"path":"\/apps\/zjhui\/LICENSE01","ctime":1391569447,"mtime":1391569447,"md5":"783b7e40cdfb4a1344d15b1f7081af66","size":35121,"isdir":0},{"fs_id":2922247596,"path":"\/apps\/zjhui\/Pcs.sh","ctime":1389857060,"mtime":1389857060,"md5":"aaeafb64fc4efcff24de3b4e92dc302f","size":3355,"isdir":0},{"fs_id":1874426057,"path":"\/apps\/zjhui\/Pcs_Uploader.sh","ctime":1389773672,"mtime":1389773672,"md5":"14d6e4f7b9daf7761a7f2aa83efaa64d","size":2653,"isdir":0},{"fs_id":2295037712,"path":"\/apps\/zjhui\/test1","ctime":1392869356,"mtime":1392869356,"md5":"5fceae3ba3777db47ed1cc6a9a96cf27","size":728,"isdir":0}],"request_id":4180656241}

利用 JSON.sh 解析后如下：

我想通过解析这json数据，然后进行组装，最后得到类似于 ./dropbox.sh list 的效果：
