Azure CLI is a cross-platform command-line tool for managing Azure resources. It supports interactive command execution and script-based automation. In this article, we organize the components and roles of two key concepts shown in the official documentation: “Change output formats” and “Query command output”.
Overview of Output and Operations in Azure CLI
When using the Azure CLI, the results returned by commands can be processed and formatted according to your use case. In the “Concepts” section of the official documentation, switching output formats and narrowing down data using queries with JMESPath are covered as important topics.
The conceptual flow from executing a CLI command to output and query application is shown below.

F --> G["Final console output"]
end
Overview of Change Output Formats
According to primary sources, the Azure CLI provides a mechanism to retrieve and change command execution results into various formats. This allows users to appropriately select a format that is visually easy for humans to verify or easy to process in subsequent scripts.
Support for Diverse Formats: It is possible to switch to output formats according to the use case, such as when checking retrieved data as-is or integrating with other tools.
Script Friendliness: By specifying a specific format within automation scripts, you can improve the efficiency of data extraction.
[Before actual device verification] Regarding the detailed behavior of specific format names and syntax, although concepts are indicated in the primary information, execution results in a local environment are not shown in this article.
Overview of Query Command Output
The “Concepts” section of the official documentation also describes query specifications for output. This is a mechanism for pinpointing and extracting only the necessary information from massive resource information or responses with complex JSON structures.
Data Filtering: By applying a query to command output results, you can exclude unnecessary properties and retrieve only the required elements.
Efficient Information Retrieval: When managing large-scale environments or numerous resources, pre-filtering the output leads to improved readability and processing speed.
Components of Related Official Documentation
In the Azure CLI documentation, a wide variety of guides and concepts are systematically organized in addition to the output and query control methods mentioned above. The main categories that can be confirmed from the primary information are as follows.
Get started / Overview: Tool overview and installation methods (Windows, Linux, macOS, Docker containers, Azure Cloud Shell, etc.).
How-To Guide: Practical operational procedures such as authentication methods, subscription management, using the Azure REST API, changing output formats, and query specification.
Concepts: Conceptual explanations such as working in interactive mode and considerations in Bash or PowerShell environments.
Fundamentals / Samples: Onboarding lists and learning resources utilizing sample repositories.
Notes on Usage
The changes to output formats and query specifications covered in this article are organized based on the concepts and components of the official documentation.
For actual command-line behavior and differences across versions, please always refer to the latest official reference.
