Please follow the below step to achieve your requirement.

I am using Ubuntu VM (Version 18.04)

Step 1: Install AZ CLI module using this below command

curl -sL https://aka.ms/InstallAzureCLIDeb | sudo bash

Step 2: Download Blob file from Storage Account to your local. Below is the picture of container and blob which will be download in local.

az storage blob download --container-name "your container name" --file "Location of file where you want to copy data" --name "Blob Name" --account-name "Storage Account name" --account-key "Storage Account Access Key"

Step 3: Check the content of the file using cat command

cat ansuman.json

Step 4: Run the following command to make changes in your json file

replace "dev" "qa" -- package.json

Step 5: Now to final upload the file in Another Container.

az storage blob upload --container-name "your conatiner name where you want to upload" --file "location of local file that is going to upload" --account-name "Storage account name" --account-key "Storage Account Access Key"
