Mastering Linux Commands: Copy Files and Folders between Multiple Servers

This article delves into the world of Linux system administration by offering an in-depth exploration of how to efficiently and securely copy files and folders between multiple systems using the scp tool. You’ll also discover the power of parallel scp (pscp) for simultaneous file transfer and how to speed up the copy process using various techniques like submitting multiple scp commands with nohup.

The corresponding video tutorial offers an additional layer of guidance with live examples and step-by-step instructions. It enriches the text content by allowing you to visually follow along and practice hands-on at your own pace.

Key Concepts Explanation

Let’s dive into the two primary commands we’ll be mastering in this article: scp and nohup.

Secure Copy (scp)

The scp command is a native tool in Linux designed for securely copying files and directories from and to a remote machine. Being part of the OpenSSH suite, it relies on the SSH protocol under the hood, ensuring secure data transfer with encryption.

For instance, to copy a local file to a remote system, we use:

scp localfile user@remote:/path/to/destination

No Hang Up (nohup)

When dealing with long-running processes, it’s crucial to ensure they continue even if the terminal is closed. This is where nohup comes in. It’s a command that allows long running processes to continue executing even after the terminal has been closed.

For example, to start a long running process with nohup, we use:

nohup command-to-run &

Hands-On Tasks

To cement your understanding of these concepts, here are tasks you can practice:

  1. Setup multiple virtual machines using VMWare or AWS EC2 instances.
  2. Transfer a directory from your local system to the remote system using the scp command.
  3. Begin a long running task with nohup and exit the SSH session. After a while, reenter the SSH session and check the nohup output file to confirm the task was completed.

Conclusion

Mastering file and directory transfer via scp and process handling with nohup are vital skills for Linux system administration. Having journeyed through this article, you’re equipped with practical knowledge to manage your files and processes effectively in a systems environment.
