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：

It’s great to use nodejs, bash script maintenance is not easy
var data = require('./data').list;
function pad(s, l) {
return s + (new Array(l - s.toString().length)).join(' ');
}
data.forEach(function (d) {
var type = d.isdir ? 'D':'F';
process.stdout.write('[' + type + '] ');
process.stdout.write(pad(d.size, 10));
process.stdout.write(d.path + '\n');
})
Get it done in minutes, easy to understand and maintain.
Assume that the file is data.json and the js file is parse.js
Just use node parse.js. If you don’t want the parse.js file, you can use the -e parameter of node in the bash script to run the js string.
