Coding Linux Shell Script to Update Postman One-Command Line

I’m tired of seeing the update Postman and the failed update in the background. And get up my knowledge and write a shell script which helps with routine.

This blog post will show you how to code a Linux shell script to update the Postman application one-command line. Link to Github gist – here

To code a Linux shell script to update Postman one-command line, you will need the following:

• A Linux computer

Steps to write update Postman one-command line

1. Create a new file and name it update_postman.sh
2. Open the file in a text editor.
3. Add the following lines to the file (or copy from gist):

#!/bin/bash

# Go to the 
cd /tmp

# Download the latest Postman source archive
wget 'https://dl.pstmn.io/download/latest/linux_64' -O postman.tar.gz

# Extract the Postman source archive
tar -xzf postman.tar.gz -C /tmp/

# Replace the existing Postman app with the new one from tmp
sudo cp -r /tmp/Postman/app /opt/postman

# Remove the old Postman source archive
rm /tmp/postman.tar.gz && rm -rf /tmp/Postman/

4. Save the file.
5. Make the file executable:

chmod +x update_postman.sh

6. To update Postman, simply run the following command:

./update_postman.sh

This script will download the latest Postman source archive, extract it to the /opt/postman folder, and then replace the existing Postman installation with the new one. It will also remove the old Postman source archive.

Postman is a software platform for API development and testing. It is used by developers, QA engineers, and other professionals to automate API testing, discover APIs, and generate documentation. Postman provides a comprehensive set of tools for managing the API lifecycle, from design to testing to deployment.

Postman’s key features include:

• API development: Postman provides a suite of tools for designing and developing APIs, such as request builders, mock servers, and code snippets.
• API testing: Postman provides a variety of tools for testing APIs, including automated testing, performance testing, and security testing.
• API discovery: Postman’s API discovery feature allows users to discover and explore APIs, both public and private.
• API documentation: Postman can automatically generate API documentation, including OpenAPI specifications and Postman Collections.
