What to watch for linux level 2

What courses should I take to successfully complete Linux Level 2 practice? I have a little experience, but for example, I had already forgotten how to configure Postfix, and it was part of the task.

Hi @OKk

You can refer to this one Learning Linux Basics Course & Labs | KodeKloud

I’m not sure if this fully covers your knowledge, but it gives you the basic understanding needed to work on KKE Linux tasks.
