Extract one file from a remote tar.gz and put it where you want it

Extracting specific files from a remote `.tar.gz` archive can be a real time-saver in DevOps workflows, especially when dealing with large files or archives containing many elements. Instead of downloading a complete archive, developers can streamline their processes by extracting only the necessary content using a few command-line tools.

To achieve this, you can use the combination of `ssh` and `tar` commands. The command structure allows you to specify the file you want to extract while directly streaming it to your local machine. This method not only saves bandwidth but also speeds up the deployment process, ensuring that your application integrations remain efficient and reliable.

A practical example could involve accessing a server where a `.tar.gz` file is stored, using `ssh` to execute the extraction of a specific file. By defining the path of the target file within the tar command, you can place it in a desired directory on your local machine instantly. This is particularly useful in scenarios where teams are collaborating on numerous projects, and rapid access to specific resources is needed without the overhead of full file transfers.

Using efficient file management practices such as this reflects key DevOps principles — automation, collaboration, and continuous integration. Embracing these techniques not only enhances productivity but also aligns well with modern development practices where time and resource management are essential for success.
