Wheels are built for various Python versions and architectures on Linux and Mac OS X. On these platforms, you should be able to install jq with a normal pip install: pip install jq If a wheel is not available, the source for jq 1.6 is downloaded over HTTPS and built. This requires: Autoreconf; The normal C compiler toolchain, such as gcc. Download for Mac it's free! DeepL Translate. Use the free DeepL Translator to translate your texts with the best machine translation available, powered by DeepL’s world-leading neural network technology. Currently supported languages are English, German, French, Spanish, Portuguese, Italian, Dutch, Polish, Russian, Japanese, and Chinese. The jQuery XML to JSON Plugin is perfect for situations where developers frequently process XML data. This happens usually from AJAX responses or when parsing RSS feeds. The plugin will allow them to easily convert the response they get into a JSON (JavaScript object), a much suitable format for running complex data processing operations in.
Extract data from APIs in Bash scripts
The jq utility is like the sed Linux utility, but for JSON. They both reformat and transform text.
The “j” in the jq program name means it queries a JSON-formatted file to produce filtered output.
On a Mac, command brew install jq reveals that the utility has a dependency of the oniguruma regular expression handler and is from Stephen Dolan’s stedolan.github.io/jq
Install
On Mac:
- brew install jq
On Ubuntu:
- apt-get install jq
On Windows Git Bash, download jq-win64.exe from github.com/stedolan/jq/releases into a bin folder in the PATH, and specify the program in commands:
- echo '{'foo': 0}' | ./jq-win64.exe .
How to jq
https://stedolan.github.io/jq/manualpresents a large (and potentially confusing) list of options.
Here’s an abridged version with examples explained step-by-step.
The ipinfo.io website returns the IP address and its metadata: location Lattitude and Longitude, postal (ZIP code), Unix time zone, carrier (org), State of the Union (region), etc.
curl ipinfo.io
yields:
NOTE: All JSON responses begin and end with curly braces between { and }.
A dot represents the entire input, but formatted with indents:
curl ipinfo.io | jq ‘.’
.[] returns each element of the array, one at a time,
curl ipinfo.io | jq ‘.[]’
If you only want one city name (with no JSON braces or quote marks):
curl ipinfo.io | jq -r .city
NOTE: jq receives a file piped in, as specified by the pipe character . To return the response in a variable within a Bash script:
CITY=$( curl ipinfo.io | jq -r .city )

### Docker Hub API
Docker Hub provides an API to access public Docker images.
curl ‘https://registry.hub.docker.com/v2/repositories/library/debian/tags/’
The response starts with:
In JSON, a left bracket ([) begin a list structure:
“results”: [{“name”: “unstable-slim”,: Yesmovies wonder woman 1984 2020 watch hd full movie online free.
Jq Tool
Note that “name” is an attribute, so would require double-quotes. ???
To return a list of just values beginning with “unstable-slim”:
curl ‘https://registry.hub.docker.com/v2/repositories/library/debian/tags/’|jq ‘.”results”[][“name”]’
???
To list the first element from the root (counting from zero):
jq ‘.[0]’

Jq Tutorial
Please enable JavaScript to view the comments powered by Disqus.Aw dang, I wish I knew about this earlier. May have made teaching command-line data processing to beginners quite a bit easier. Example lesson using Spotify API (which is still public and free):(just noticed that you used the Spotify API too for the demo :) https://github.com/dflemstr/rq/blob/master/doc/demo.md)
I personally like using jq but not sure how easy-to-grok it is for people who are new to both the command-line and to serialized data structures in general. Will have give rq a spin (waiting for it to compile on my machine) but it looks quite nice, at least for my own uses, which heavily involve YAML.

In terms of TSV/CSV support, you may want to checkout csvjson, which is part of the csvkit command-line suite: http://csvkit.readthedocs.io/en/0.9.1/scripts/csvjson.html
Jq Tool For Mac Free
csvkit is my go-to tool for data, so much that I rarely ever use SQL for anything other than when I actually need a database. I suppose if rq were to be my go-tom missing it in the documents, there doesn't appear to be a way to convert to CSV? That would be helpful. FWIW, csvkit has a tool named in2csv, which will read from line-delimited JSON:
