Overview of this book

Developers are always looking to raise their game to the next level, yet most are completely lost when it comes to the Linux command line. This book is the bridge that will take you to the next level in your software development career. Most of the skills in the book can be immediately put to work to make you a more efficient developer. It’s written specifically for software engineers, not Linux system administrators, so each chapter will equip you with just enough theory to understand what you’re doing before diving into practical commands that you can use in your day-to-day work as a software developer. As you work through the book, you’ll quickly absorb the basics of how Linux works while you get comfortable moving around the command line. Once you’ve got the core skills, you’ll see how to apply them in different contexts that you’ll come across as a software developer: building and working with Docker images, automating boring build tasks with shell scripts, and troubleshooting issues in production environments. By the end of the book, you’ll be able to use Linux and the command line comfortably and apply your newfound skills in your day-to-day work to save time, troubleshoot issues, and be the command-line wizard that your team turns to.

In the sections below we will explore the sftp and scp commands for file transfer. Going through a few examples using these commands will help you understand how you can handle files in most situations. That said, we will also cover file transfer without SFTP or SCP, in case they are disabled on the server.

SFTP

While OpenSSH is frequently used as a way to log in to remote systems, it also allows for file transfer independently of a login session. This is usually accomplished via the SFTP subsystem. Though SFTP resembles File Transfer Protocol (FTP), it is actually a completely custom protocol. Like FTP, SFTP allows authenticated users to transfer files to and from remote servers. Unlike FTP, which is insecure, SFTP’s authentication and file transfers are secure and fully encrypted.

There are many FTP clients that also support SFTP. One famous example is Filezilla, which has an excellent graphical user interface. However, since this is a book about...
