Performing simple Azure Table Storage REST API operations using curl command.

The blog provides guidance to perform simple Table Storage REST API operations such as Create table, Delete Table, Insert entity, Delete entity, Merge entity, Get Table properties, Get Table Storage Stats, Query Table, Query Entities and Update entities operations using curl command.

Let us look at some of the command syntax to perform REST API operations and we will be making use of SAS token as the authentication mechanism. We need to take care of the pointers below while performing the operations via curl command:

Ensure the URL is formed correctly as per the operation you are trying to perform.
The mandatory header needs to be passed along with correct values for it.
Ensure you are appending/removing extra ‘?’ to the SAS token in the URLs accordingly.
Http verb can be GET, PUT or DELETE as provided by the REST API specifications.

So let's began:
