以 JSON 格式输出文件夹的磁盘空间

Question

我想使用以下命令将文件夹的大小输出到 json 文件

tree -d -JL 3 --charset utf-8 --du $HOME/share >> discspace.json

但该命令不会输出有效的 json。相反，它输出以下内容：

[
  {"type":"link","name":"/home/user/share","contents":[
    {"type":"directory","name":"folder1","size":16384,"contents":[
      {"type":"directory","name":"folder1_1","size":4096,"contents":[]},
      {"type":"directory","name":"folder1_2","size":4096,"contents":[]},
      {"type":"directory","name":"folder1_3","size":4096,"contents":[]}>>,<<
    ]},
    {"type":"directory","name":"folder2","size":20480,"contents":[
      {"type":"directory","name":"folder2_1","size":4096,"contents":[]},
      {"type":"directory","name":"folder2_2","size":8192,"contents":[
        {"type":"directory","name":"folder2_2_1","size":4096,"contents":[]}>>,<<
      ]},
      {"type":"directory","name":"folder2_3","size":4096,"contents":[]}>>,<<
    ]}>>,<<
  ]},
  {"type":"report","size":36881,"directories":9}
]

当验证 json 时，我收到错误，因为使用了太多逗号（我用 标记的逗号>>,<<）。

哪个命令更好/正确？
