# Linux- cheat sheet: a Russian-language command reference

> The justxor/Linux- repository is a single README that collects Linux and Bash commands with theory, examples and practice tasks, written in Russian and organised with a colour-coded difficulty legend. It suits a Russian-speaking beginner or candidate preparing for LPIC or RHCSA, and it is a document to read rather than a tool to install.

## A README that is the entire project

The justxor/Linux- repository is unusual in a way worth stating first. The top level of the tree contains a README and one image file, and there is no code, no package, no build system and no release history. The repository has no GitHub releases, the last push was on 2026-10-04, and the primary language and licence are both recorded as unknown even though the README carries an MIT badge and a Russian-language badge. So this is a document, not a project in the code sense, and the homepage is a Telegram channel at t.me/linuxkalii. The content is a Linux and Bash cheat sheet in Russian, and the description calls it the most convenient cheat sheet for Linux and Bash in that language, with theory in plain language, terminal commands, access rights, processes, network, SSH, systemd, grep, sed, awk, Vim and ready-made one-liners, all with examples.

## The colour legend, which tells you how to read it

The cheat sheet has a legend with four markers, and it is the most useful thing in the document for a newcomer. Green means base level, something you need to know regardless. Yellow marks an advanced level. Red is the one that matters most: it marks commands that are dangerous and can delete data or break the system. And a lightbulb marks a tip or a life hack, the kind of shortcut that usually comes from someone having already made the mistake. The same markers reappear on the section headings in the table of contents, so the advanced Bash section, the LVM and RAID section, the advanced networking section and the performance and tracing section are all marked yellow, while the system recovery section is marked red. That structure lets a reader open the document at the level they need and ignore the rest, which is the difference between a reference you read and a wall you do not.

## Theory first, then commands

The table of contents opens with a section on how Linux is built, and its stated rationale is the sentence that makes the document work: commands are forgotten, understanding remains. That section covers the kernel, files, inodes, permissions, processes, threads, PATH, quoting, memory, boot, filesystems, packages, network and SSH keys, and it explains why everything else behaves the way it does, so the rest of the cheat sheet is easier to read afterwards. The kernel layer diagram in that section separates the user, the shell or graphical environment, the utilities and libraries such as coreutils and glibc, the system call boundary with open, read and fork, the Linux kernel handling processes, memory, filesystems, network and drivers, and the hardware below. A glossary of terms closes the document, with definitions for the kernel, the distribution, user space versus kernel space, the terminal, and the console or TTY, alongside the `uname -r` command for checking the kernel version.

## The command sections, from navigation to cron

The core of the document is a numbered sequence of command groups that follows a sensible order for someone learning the system. It starts with first steps and help, then navigation of the filesystem, working with files and directories, and viewing file contents. Search comes next with find, locate and grep, then access rights with chmod and chown, then users and groups with sudo. The process section covers processes and signals, followed by system information, disks and filesystems, and the network. Then SSH, SCP and rsync, archives and compression, and the package managers, with apt, dnf and pacman named in the heading, which is a small but useful signal that the document does not assume one distribution. The last of the core run are systemd and services, logs with journalctl, text processing with sed, awk, cut and sort, redirection, pipes and xargs, Bash variables and scripts, terminal hotkeys, Vim minimum to survive, cron as the task scheduler, the firewall with ufw, firewalld and iptables, the FHS directory structure, and useful one-liners.

## The advanced sections, and what they assume

Beyond the base material the document adds a professional track, and the topics are the ones an operations engineer is expected to know rather than guess. Bash for professionals covers arrays, parameter expansion and trap. LVM, RAID and snapshots is a section of its own. Then advanced networking, performance and tracing, systemd for professionals, and the kernel with sysctl, modules, limits and cgroups. Security and hardening follows, then containers from the inside with namespaces, Docker and Podman. The system recovery section is the one marked red, which tells you the document's author considers it the most dangerous material in the file, and the interview questions section is aimed at the same audience. The stated audience is broad, ranging from beginner Linux users and students to DevOps and SRE engineers, system administrators, developers, and anyone preparing for an interview or an exam such as LPIC, RHCSA or Linux+. The stated compatibility is Ubuntu, Debian, Linux Mint, CentOS, RHEL, Rocky, AlmaLinux, Fedora, Arch, Manjaro, openSUSE, WSL and macOS for most commands.

## Practice: eight scenarios and 28 tasks

The document closes its teaching material with two practice sections, and they are what separate it from a plain reference. There is a section of eight step-by-step scenarios drawn from real work, described as practical step-by-step recipes, and a workshop section with 28 tasks with solutions on a training ground environment. The distinction in the wording matters, because the tasks are not framed as things to run on a work machine. The scenarios are explicitly recipes for real situations, while the exercises assume an environment set aside for practice. That is a sensible split for a document that includes a red-marked system recovery section, and it is the same reason the dangerous command list has its own numbered section in the table of contents, as a chapter 37 sitting between the diagnosis section and the practical scenarios.

## The limits of a document like this

Two things are worth knowing before you treat it as a reference. The first is that the whole thing is in Russian, so it serves a Russian-speaking reader specifically, and the description makes a point of that with a language badge and a channel ecosystem around it. The second is that a cheat sheet is not a substitute for the man pages. Commands have options, and the document is organised around the command and a few common flags, so anything beyond the common case needs the actual documentation. The README also leans heavily on Telegram, with the author channel, a machine learning channel, a Linux books channel and a collected list of Linux resources, so the repository is the front of a content ecosystem rather than a self-contained artifact. The MIT badge is there, but the licence is recorded as unknown, so anyone copying content out of it should confirm the terms from the project itself rather than from the badge.

## Conclusion

Adopt the Linux- cheat sheet if you read Russian and want one document that covers Linux commands, Bash scripting and interview preparation in a single place, since the theory-first ordering and the practice tasks are what distinguish it from a command list. Skip it if you need English-language material, since the whole document is in Russian, and remember it is a README with no releases and no versioning, so the content changes in place. Before you rely on it, note that the legend flags individual commands as dangerous, and that the exercise section assumes a training ground environment rather than a production machine.
