UbuntuEd 24.05: Container Management in Ubuntu, Website Redesign and More

The new look of Learn Ubuntu is here.


You may have noticed something. Learn Ubuntu does not look the same.

That's right! I have changed the design of the website to provide you with a more streamlined Ubuntu learning experience.

Articles on the same topics are now grouped together. Take this page for example:

Using Firewall With UFW in Ubuntu
Ubuntu comes with UFW (Uncomplicated Firewall) installed by default. It is called uncomplicated firewall because it makes things a lot easier than using something iptables or nftables for creating firewall rules. But this doesn’t mean that there is no learning curve involved. You do need to learn how to use

Individual topics that are not part of a group remain standalone.

I hope you like this new layout. Let me know what you think of it by replying to this email.

In this edition, we will be focussing on Container Management with Docker and Podman.

🪧 Working with Docker and Podman in Ubuntu

Containers are isolated units with their own software and settings that share one operating system, use fewer resources than virtual machines, and communicate through specific channels.

Docker is super popular for containers, but it's not the only game in town! In this edition, we will explore how to work with both Docker and Podman!

Try something other than Docker? 🚀 Check out Podman by Red Hat—a fully open-source alternative!
This article, shows you how to install Podman on Ubuntu.

💡 Command Line Tips

You can print the line number while using the cat command to print text file contents.

The -n option will give line numbers to empty lines as well.

cat -n <filename>

While, the -b option will print line numbers only to non-empty lines in the file.

cat -b <filename>
