Introduction

Modern command line programs are becoming increasingly popular due to their efficiency, speed, and flexibility. They are often written in Rust, a modern programming language that is designed for performance, safety, and concurrency. Rust is a great choice for CLI tools because it provides low-level control over system resources, making it ideal for building high-performance applications.

This cheatsheet covers the basics of CLI tools, Rust programming language, and related topics that will help you get started with modern CLI programs.

CLI Basics

Before diving into modern CLI tools, it's important to understand the basics of CLI. Here are some key concepts to keep in mind:

Command Line Interface (CLI): A text-based interface used to interact with a computer system. CLI tools are often used for automation, scripting, and system administration tasks.
Terminal: A program that provides a CLI interface to the user. It allows users to enter commands and receive output from the system.
Shell: A program that interprets user commands and executes them on the system. The most common shells are Bash, Zsh, and Fish.
Command: A specific instruction given to the system through the CLI. Commands are often composed of a command name and arguments.
Argument: A value passed to a command that modifies its behavior. Arguments can be optional or required.
Option: A type of argument that modifies the behavior of a command. Options are often preceded by a dash (-) or double dash (--) and can be short (e.g., -h) or long (e.g., --help).
Environment Variables: Variables that are set in the system environment and can be accessed by CLI tools. They are often used to store configuration information or system settings.

Rust Programming Language

Rust is a modern programming language that is designed for performance, safety, and concurrency. It is a great choice for building CLI tools because it provides low-level control over system resources, making it ideal for building high-performance applications. Here are some key concepts to keep in mind:

Ownership and Borrowing: Rust's ownership and borrowing system ensures that memory is managed safely and efficiently. It prevents common programming errors such as null pointer dereferencing and memory leaks.
Concurrency: Rust provides built-in support for concurrency through its lightweight threads called "tasks". Tasks can communicate with each other using message passing.
Cargo: Rust's package manager, Cargo, makes it easy to manage dependencies and build projects. It provides a simple way to create, build, and publish Rust packages.
Crates: Rust packages are called "crates". They can be published to the Rust package registry, crates.io, and can be easily installed using Cargo.

CLI Tools

There are many modern CLI tools available that are often written in Rust. Here are some popular tools that you should know about:

Ripgrep: A fast and powerful text search tool that uses Rust's regex engine. It is designed to be faster than grep and other similar tools.
Fd: A simple and fast alternative to the find command. It is designed to be faster than find and provides a simpler syntax.
Bat: A cat clone with syntax highlighting and Git integration. It is designed to be a more user-friendly alternative to cat.
Exa: A modern replacement for the ls command. It provides a more user-friendly output and supports color coding and Git integration.
Zoxide: A smarter cd command that tracks your most frequently used directories. It provides a faster and more efficient way to navigate your file system.
Starship: A customizable prompt for your shell. It provides a more informative and user-friendly prompt that can be customized to your liking.

Text Editors

Text editors are an essential tool for developers and system administrators. Here are some popular text editors that you should know about:

Vim: A highly configurable text editor that is designed for efficiency and speed. It provides a powerful set of features for editing text and can be customized to your liking.
Emacs: A highly extensible text editor that is designed for customization and flexibility. It provides a powerful set of features for editing text and can be customized to your liking.
VS Code: A modern and popular text editor that is designed for ease of use and productivity. It provides a wide range of features and extensions for editing text and developing software.
Sublime Text: A fast and lightweight text editor that is designed for speed and efficiency. It provides a powerful set of features for editing text and can be customized to your liking.

Version Control Systems

Version control systems are essential for managing code and collaborating with others. Here are some popular version control systems that you should know about:

Git: A distributed version control system that is designed for speed and efficiency. It provides a powerful set of features for managing code and collaborating with others.
Mercurial: A distributed version control system that is designed for ease of use and flexibility. It provides a powerful set of features for managing code and collaborating with others.
SVN: A centralized version control system that is designed for simplicity and ease of use. It provides a simple set of features for managing code and collaborating with others.

Package Managers

Package managers are essential for managing dependencies and installing software. Here are some popular package managers that you should know about:

Cargo: Rust's package manager that makes it easy to manage dependencies and build projects. It provides a simple way to create, build, and publish Rust packages.
NPM: Node.js' package manager that makes it easy to manage dependencies and build projects. It provides a simple way to create, build, and publish Node.js packages.
Homebrew: A package manager for macOS that makes it easy to install software and manage dependencies. It provides a simple way to install and manage software on macOS.

Containers

Containers are a lightweight and efficient way to package and deploy software. Here are some popular container technologies that you should know about:

Docker: A container platform that makes it easy to package and deploy software. It provides a simple way to create, build, and deploy containers.
Podman: A container platform that provides a simple and secure way to run containers. It is designed to be a drop-in replacement for Docker.
Kubernetes: A container orchestration platform that makes it easy to manage and deploy containers at scale. It provides a powerful set of features for managing containerized applications.

Conclusion

This cheatsheet covers the basics of modern CLI tools, Rust programming language, and related topics that will help you get started with modern CLI programs. Remember that CLI tools are designed to be efficient, fast, and flexible, and Rust is a great choice for building high-performance CLI applications. Keep exploring and experimenting with different tools and technologies to find the ones that work best for you. Happy coding!
