Welcome to my blog!
This site is intended for anyone working with Linux who has encountered problems and is seeking quick solutions or simply wishes to study Linux. This is not an ordinary blog and is not updated regularly. I have organized Linux-related subjects into several topics, and as I find new information, solutions, and interesting material, I will add it to its respective topic. You can read about many things in the world of Linux here.
The structure of each subject is very similar. First, I provide a general overview of the topic with the most important terms and definitions. Then, I include some important/useful commands that are likely needed for everyday work. Finally, I offer solutions to common situations that could arise during the daily work of an administrator.
I have endeavored to keep explanations as simple as possible so that navigation through this site should be easy without any additional instructions. All materials included here were gathered by me through personal experience, forums, and other internet sources. If I come across interesting data that I think is valuable, I will publish it on this blog. Essentially, this blog represents my personal viewpoint on Linux-related topics and is not an official site. While most of the content has been successfully tested, please note that you may encounter typos, missing steps, and erroneous data (I cannot guarantee that everything will work perfectly), so please examine and consider carefully before taking action.
I hope you find this site helpful for your work!
