有没有一种方法可以验证Unix中JSON文件的语法并将无效文件移到错误文件夹中。

谢谢，凯文（Kavin）

您可以尝试使用python oneliner：

python -c "import json;file = open('foo.json');json.loads(file.read());file.close()"

通过一些调整，您可以将其转换为别名：

testjson(){
    python -c "import json;file = open('$1');json.loads(file.read());file.close()"
}

并使用类似这样的内容：

ls | while read file;
  testjson $file || mv $file ~/bad_json/
done;

一些带有此示例：

echo "{}" > foo.json

echo "{" > bar.json

testjson bar.json && echo ok 
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python2.7/json/__init__.py", line 338, in loads
    return _default_decoder.decode(s)
  File "/usr/lib/python2.7/json/decoder.py", line 366, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/lib/python2.7/json/decoder.py", line 382, in raw_decode
    obj, end = self.scan_once(s, idx)
ValueError: Expecting object: line 1 column 2 (char 1)

testjson bar.json || echo ko
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python2.7/json/__init__.py", line 338, in loads
    return _default_decoder.decode(s)
  File "/usr/lib/python2.7/json/decoder.py", line 366, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/lib/python2.7/json/decoder.py", line 382, in raw_decode
    obj, end = self.scan_once(s, idx)
ValueError: Expecting object: line 1 column 2 (char 1)
ko

testjson foo.json && echo ok
ok

testjson foo.json || echo ko

注意：请小心包含'或\n的特殊文件名

验证（在某种程度上）我的 test_0009 目录中的 1660 个 jsonld 文件。全部都有“0”退出代码（=“OK”）：

[pjalajas@sup-pjalajas-2 504Project]$ find test_0009 -iname "*.jsonld" | parallel "jq '.' 2> /dev/null ; echo $?" | cut -d\  -f1 | sort | uniq -c | sort -k1nr
   1660 0
