AWS Lambda : Export all AWS Lambda function with code in a single go using AWS CLI [For backup]

To export all AWS Lambda functions in a single Go using AWS CLI, you can use the following steps:

Install and configure the AWS CLI on your local machine or server.
Open a terminal or command prompt and enter the following command to list all your Lambda functions:

aws lambda list-functions --query 'Functions[*].FunctionArn' --output text

This will return the ARN (Amazon Resource Name) of each Lambda function in your account, separated by newlines.

To export all AWS Lambda functions in a single Go using AWS CLI, you can use the aws lambda list-functions command to get a list of all your Lambda functions and then use a loop to export the code for each function to a separate file.

Here’s an example bash script that exports all Lambda functions in a single command:

#!/bin/bash

# Export all Lambda functions
for func in $(aws lambda list-functions --output text --query 'Functions[*].FunctionName'); do
  echo "Exporting function: $func"
  aws lambda get-function --function-name $func --query 'Code.Location' --output text | xargs wget -O "$func.zip"
done

Save this script as a file (e.g., export-lambda.sh) and make it executable using the chmod command:

chmod +x export-lambda.sh

Then, run the script using the following command:

./export-lambda.sh

This script will loop through all your Lambda functions and export the code for each function to a separate zip file with the function name as the file name. The exported zip files will be saved in the current directory where you run the script.
