JSON is the "Javascript Object Notation", basically a file format for

|
|
|
data that's suitable for easy processing by most modern web-based tools.

If you're looking to parse JSON from the command line with a minimum of
|
|
|
|
|
code, the `jq` program may be your thing. `jq` is a filter that takes
|
|
|
|
|
JSON on standard input and produces JSON on standard output. Along the
|
|
|
|
|
way in the middle you can do various standard sorts of file munging on
|
|
|
|
|
a field by field basis.

[Documentation for `jq` is in its manual.](http://stedolan.github.io/jq/manual/)
