Shell scripting with Aws

Introduction

After successfully installing and creating your AWS EC2 instance, let's delve into the world of shell scripting by implementing a popular GitHub API. This script will allow you to view the list of collaborators and remove someone from it, addressing the common issue of revoking permissions when a person leaves an organization or a project.

AWS EC2 Instance Setup

Start by creating an AWS instance using the following image:

Connect your CLI to your EC2 instance and clone the GitHub repository with the following command:

git clone https://github.com/surajvast1/shell-script 

GitHub Collaboration Test

Create a GitHub organization and add a collaborator to test your script. Run the following set of commands in your terminal:

cd shell-scripting-projects/github-api export username="<organization_username>" export token="<github_access_token>" ./list-users.sh <repo_owner> <repo_name> 

For example:

cd shell-scripting-projects/github-api export username="surajvast1" export token="ghp_sAJKxxxxxxxxxxxxxxxxxxxxxxxxxx" ./list-users.sh surajvast1 shell-script 

jq Information

The script utilizes jq to access only the names of collaborators from the JSON response.

Advanced Scripting with Helper Function

To enhance the shell script, a helper function can be added. Here is an example:

function helper { expected_cmd_args=2 if [ $# -ne $expected_cmd_args ]; then echo "Please execute the script with the required cmd and args" echo "./list-users.sh <repo_owner> <repo_name>" fi } 

This function ensures that the script is executed with the correct number of command-line arguments.
