Hey there,

Feels like 2025 is ending sooner than expected. I know that's not the case but it just feels like that 😄

On that note, we plan to publish at least two more courses for you before the year ends. They are likely to be on Terraform and Kubernetes. I am also planning a microcourse on 'automated backups with cron and rsync'. These classic Linux tools are always reliable.

And in the meantime, we are also working on expanding our collection of hands-on practice labs so that you can improve your skills by doing it.

Lots of things planned. Stay tuned, stay subscribed.

Here's why you should get LHB Pro membership:

✅ Get access to Linux for DevOps, Docker, Ansible, Systemd and other text courses
✅ Get access to Kubernetes Operator and SSH video course
✅ Get 6 premium books on Bash, Linux and Ansible for free
✅ No ads on the website

💡Quick terminal tip

You can extract selected files from an archive without extracting everything using tar command.

First, check the contents using:

tar -tf archive.tar.gz --wildcards "*.txt"

Now, extract the selected files.

tar -xf archive.tar.gz --wildcards "*.txt"
