json.sh

json.sh is a very portable JSON parser-- it should work in just about any shell you throw at it. It can parse and output variables from a JSON file in a more script-friendly form.

This is an old hacked-together script of mine that I’m only posting because I’m sentimental. Don’t use it; I would instead recommend the beautiful program gron.

Usage

To use json.sh, you can simply run json.sh with a filename as an argument. Here's an example command and it's output:

$ sh json.sh example.json
/animals
/animals/pig
/animals/pig/tail
/animals/pig/tail = curly
/animals/pig/nose
/animals/pig/nose = adorable
/animals/sheep
/animals/sheep/tail
/animals/sheep/tail = short
/animals/sheep/nose
/animals/sheep/nose = ugly

There are also a few useful arguments you should keep note of:

argument	description
-v $string	Only print variables with the name $string.
-s $string	Only print the value of the variable $string.
-V $string	Only print variables with the value $string.
-o $string	Only print the object $string.

With -v and -s, for example, $string could be anything from tail to /pig/tail to /animals/pig/tail. Same syntax goes for -o. -V is the only odd one out-- it's $string needs to be a variable's value, like adorable from /pig/nose.
