Linux command line, privilege escalation: su, sudo commands

Wed, 11 Sep 2024 00:00:00 +0000

Greetings!

We continue studying the Linux command line. Today we’ll learn how to properly run commands on behalf of another user, including the root user. We’ll get familiar with the su and sudo commands, and also learn how to correctly grant limited privileges to users and groups.

Along the way, let’s figure out why sudo su is like saying: “Open the door for me,” and then demanding again: “And let me in right now!"😁.

Greetings!

A new release of the Linux Mint 22 distribution (based on Ubuntu 24.04) codenamed Wilma has just come out. And just recently the developers prepared instructions and a tool for a native (without reinstalling the OS) system upgrade, from Linux Mint 21.3 to Linux Mint 22. In this short note I’ll demonstrate this simple process 😉

I’d like to note that my test system has been upgraded this way since Linux Mint 20. Still alive so far)

Greetings!

I present to your attention the first (introductory) part of a series of posts devoted to working in the Linux command line. This post is a kind of foundation for future entries on this topic. It will be followed by posts with descriptions and practical examples of using popular console utilities.

I’ll give one recommendation right away. If you want a comprehensive resource on the Linux command line, I recommend reading William Shotts’ book with the simple title: The Linux Command Line. This book is an excellent source that lets you thoroughly study the basics of working in the Linux console. Material from this book will also be used and quoted in this and future posts about Linux.

Installing Windows Applications on Linux

Wed, 08 Jun 2022 00:00:00 +0000

Greetings!

Today I’ll show you how to run programs designed for Windows on Linux Mint 20, which we previously installed and configured.

I’ll warn you right away that not all Windows applications work correctly on Linux. It all depends on how complex and heavy the application’s design is. Nevertheless, a large number of Windows programs run on Linux without any problems, and today I’ll demonstrate this to you.

Introduction

There is open-source software for running Windows applications in a Linux environment — Wine. There are many articles on the internet about installing it on Linux Mint, and they all differ from one another. I’ve often come across non-working instructions and had to tinker a lot by hand. In this note I will try to describe a working, and at the same time simple, installation option for Linux Mint 20.

⚠️ Warning

Right away, I want to point out that everything described in this guide, you do at your own risk. If you have experience reinstalling or restoring Windows systems, then you have nothing to worry about. But just in case, before you start, back up your important files to another partition, or better yet, to a removable drive.
