bat

bat is a cat clone with syntax highlighting and Git integration that works on Windows, MacOS and Linux. It provides syntax highlighting for many file extensions by default.

exa

exa is a modern replacement for ls, the default command-line program in Unix/Linux for listing directory contents. exa supports icons with the --icons flag.

just

A command runner and partial replacement for make

Just create a justfile with the desired commands and your set.

When running with PowerShell, add the following at the start of your justfile:

set windows-shell := ["pwsh.exe", "-NoLogo", "-NoProfile", "-Command"]

fd

fd is a fast and user-friendly alternative to find, the built-in command-line program in Unix/Linux for walking a file hierarchy. fd provides opinionated defaults for the most common use cases. To find a specific file by name, you write fd PATTERN instead of find -iname ‘*PATTERN*’. fd is also extremely fast and it comes with a ton of options like ignoring hidden directories, files and patterns from .gitignore by default.

procs

procs is a modern replacement for ps, the default command-line program in Unix/Linux for getting information about processes. It provides convenient, human-readable (and colored) output format by default.

sd

sd is an intuitive find & replace command-line tool, it is an alternative to sed, the built-in command-line program in Unix/Linux for parsing and transforming text (). sd has simpler syntax for replacing all occurrences and it uses the convenient regex syntax that you already know from JavaScript and Python. sd is also 2x-11x faster than sed.

sed is a programmable text editor, with search and replace being a common use case. In that light, sd is more like tr, but on steroids. (thanks /u/oleid for the suggestion).

dust

dust is a more intuitive version of du, the built-in command-line program in Unix/Linux for displaying disk usage statistics. By default dust sorts the directories by size.

startship

The minimal, blazing-fast, and infinitely customizable prompt for any shell.

ripgrep

ripgrep is an extremely fast alternative to grep, the built-in command-line program in Unix/Linux for searching files by pattern. ripgrep is a line-oriented search tool that recursively searches your current directory for a regex pattern. By default, ripgrep respects .gitignore and automatically skips hidden files, directories and binary files.

toeki

tokei is a program that displays statistics about your code. It shows the number of files, total lines within those files and code, comments, and blanks grouped by language.

hyperfine

hyperfine is a command-line benchmarking tool. Among many features, it provides statistical analysis across multiple runs, support for arbitrary shell commands, constant feedback about the benchmark progress and current estimates and more.

ytop

ytop is an alternative to top, the built-in command-line program in Unix/Linux for displaying information about processes.

tealdeer

tealdeer is a very fast implementation of tldr, a command-line program for displaying simplified, example based and community-driven man pages.

bandwhich

bandwhich is a CLI utility for displaying current network utilization by process, connection and remote IP or hostname.

grex

grex is a command-line tool and library for generating regular expressions from user-provided test cases.

rmesg

rmesg is a dmesg implementation in Rust (and available as a library for Rust programs to consume kernel message logs.)

zoxide

zoxide is a blazing fast autojumper, intended to completely replace the cd command. It allows you to change directories without typing out the entire path name.

delta

delta is a viewer for git and diff output. It allows you to make extensive changes to the layout and styling of diffs, as well as allowing you to stay arbitrarily close to the default git/diff output.

tp-note

Tp-Note is a template tool that enhances the clipboard with a save and edit as a note file function. After creating a new note file, Tp-Note launches the user’s favorite file editor (for editing) and web browser (for viewing).

nushell

nushell is a new type of shell, written in Rust. Its goal is to create a modern shell alternative that’s still based on the Unix philosophy but adapted to the current era. It supports piping and filtering in a way similar to awk and sed with a column view so that you can combine operations like in SQL. (thanks /u/matu3ba for the suggestion).

Introduction

From Wikipedia, the free encyclopedia:

Rust is a multi-paradigm programming language focused on performance and safety, especially safe concurrency. Rust is syntactically similar to 

Rust was originally designed by Graydon Hoare at Mozilla Research.

It has gained increasing use in industry and is now Microsoft’s language of choice for secure and safety-critical software components.

Rust has been the “most loved programming language” in the Stack Overflow Developer Survey every year since 2016.

Rust could be used in different areas

• Web Assembly
• Embedded Programming
• Command Line Utilities
• Operating System Developmend (see Redox OS)

  Rustup

  Download install script and run it

  curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

  Modify .bashrc to add Rust path to PATH

  source $HOME/.cargo/env

  Other way to install Rust on MacOS

  brew install rust

  Create and run your first App

  Create the app

  $ cargo new hello_world
  $ cd hello_world

  Show folder structure

  $ tree .
  .
  ├── Cargo.lock
  ├── Cargo.toml
  └── src
      └── main.rs

  1 directory, 3 files

  Show main source file

  fn main() {
      println!("Hello, world!");
  }

  Build your app

  $ cargo build
  Compiling hello_world v0.1.0 (.../hello_world)
  Finished dev [unoptimized + debuginfo] target(s) in 6.32s

  Or build a production ready version

  $ cargo build --release<br>Finished release [optimized] target(s) in 0.19s

  Run your app

  $ cargo run
  Finished dev [unoptimized + debuginfo] target(s) in 0.04s
  Running `target/debug/hello_world
  Hello, world!

  Add functionality to your app

  Add Dependencies

  Let’s add a dependency to our application. You can find all sorts of libraries on crates.io, the package registry for Rust. In Rust, we often refer to packages as “crates.”

  In this project, we’ll use a crate called ferris-says.

  In our Cargo.toml file we’ll add this information (that we got from the crate page):

  [dependencies]
  ferris-says = "0.1"

  Modify main source

  Now let’s write a small application with our new dependency. In our main.rs, add the following code:

  use ferris_says::say; // from the previous step
  use std::io::{stdout, BufWriter};
  
  fn main() {
      let stdout = stdout();
      let message = String::from("Hello fellow Rustaceans!");
      let width = message.chars().count();
  
      let mut writer = BufWriter::new(stdout.lock());
      say(message.as_bytes(), width, &mut writer).unwrap();
  }
