10 Resolve a JSON pointer on JSON files
11
12 positional arguments:
13 POINTER File containing a JSON pointer expression
14 FILE Files for which the pointer should be resolved
15
16 optional arguments:
17 -h, --help show this help message and exit
18 --indent INDENT Indent output by n spaces
19 -v, --version show program's version number and exit
20

22 The following shows example usage ::
23
24 $ cat a.json
25 { "a": [1, 2, 3] }
26 $ cat b.json
27 { "a": {"b": [1, 3, 4]}, "b": 1 }
28 $ cat ptr.json
29 "/a"
30 $ jsonpointer ptr.json a.json b.json
31 [1, 2, 3]
32 {"b": [1, 3, 4]}
