Linux: Run a Single Command across Multiple Servers with SSH

"You don't always need third-party software to control multiple Linux servers — not when a bit of scripting magic can get the job done."

Linux offers various ways to reach the same destination. This is part of its strength: You decide how you want to get from A to B. Imagine it as "Mad Libs," the operating system equivalent.

Consider, for example, the ability of remote machines to execute commands. Many options exist, such as Red Hat, Ansible, and Puppet, which are amazing platforms but might be overkill for what you need.

Imagine you have to manage a workstation and five or ten servers. You can use the workstation to Secure Shell each server and run the necessary commands. Then, you can exit the server and rinse and repeat.

This can be time-consuming and lead to issues. Imagine running the wrong command on the wrong machine. You do not want to experience that.

This handy SSH tip will make your life easier! Let's look at how to run a single command across multiple servers with SSH.
