It is not designed for structured data and does not interpret nested braces properly.
It reads text line by line and re-evaluates the script each time. sed expects to receive lines of data separated by new lines.sed can process a variety of text-based file formats. jq expects JSON data and is not used with other types of data.Here is an analysis of the similarities and differences between the applications and their relative strengths. However, there are significant differences between the two applications. Both commands can parse text and filter and transform it. Jq is often compared to the standard Linux sed command. Here are some of the available resources.įull language description on the jq GitHub page.Ĭookbook showing how jq can be used for complex tasks, such as recursively deleting elements from objects. For example, it can receive input from the terminal and send its output to another Linux utility, such as find. It can be integrated with other programs or processes.
Jq uses a piping mechanism to chain filters together and constructs complex data transformations. Standard mathematical and logical operators allow users to parse a file for entries satisfying a boolean expression. jq greatly simplifies array processing because it can iterate through an entire array and display a particular entry. jq aligns brackets, applies proper spacing and indentation rules, and displays each property on its own line.Ī large number of built-in functions are used to extract certain values or array entries. Many users rely on jq to properly format JSON files because it always displays JSON information in a “pretty” format. Jq is a command-line utility that can slice, filter, and transform the components of a JSON file.

It is written in the C programming language and is completely portable to other systems, with no runtime dependencies. jq is available for most systems and can be installed using a variety of package managers or directly as a binary. Users had to rely on grep, sed, and other Linux commands, or write their own functions. Traditionally, there were few good tools for working with JSON data. Jq was developed specifically to address the need for a JSON processor. Lists are enclosed in square brackets, and curly brackets.Here are some highlights of the JSON specification. The data in a JSON file can usually be understood even without an API. This makes it a useful mechanism for data exchange, especially between web applications and servers. JSON is derived from JavaScript and is designed as an open standard to be both language-independent and self-describing. JSON has become one of the most widely used standards for exchanging data due to its flexibility and intuitive, human-readable structure. Jq is used to process JavaScript Object Notation (JSON) data.

This guide introduces the jq application and explains how to install and use it. It features a powerful set of filters and functions that can manipulate, analyze and transform JSON data.
It allows users to display a JSON file using standard formatting, or to retrieve certain records or attribute-value pairs from it.
JSON processor that is flexible and straightforward to use.
