sudo vs su vs root (Privilege Management Guide) | Linux for DevOps & Cloud
Understanding sudo, su, and the root user is one of the most important concepts in Linux — especially if you're preparing for DevOps, Cloud, or System Admin roles.
Most beginners use these commands daily…
But don’t truly understand the difference.
And in real-world production environments, this knowledge is critical.
Using the wrong privilege level can lead to permission errors, security risks, or even system failure.
💡 In this video, you’ll learn:
What is the root user in Linux
What is sudo and how it works
What is su (switch user)
Difference between sudo vs su vs root
When to use each command in real DevOps scenarios
Why direct root access is risky in production
Best practices for privilege management
🔥 Why this matters for DevOps:
In real DevOps workflows, you don’t get full access by default.
You must understand how to safely elevate privileges without breaking systems.
This is also one of the most commonly asked topics in Linux and DevOps interviews.
🎯 Who should watch:
