Rewritten in Rust: Modern Alternatives of Command-Line Tools

After a prolonged period of inactivity, new devs have taken over to support
htop. The new 3.0 release features lots of improvements (
https://github.com/htop-dev/htop/blob/master/ChangeLog ), mostly to
underlying low-level items.

eDEX-UI is an open-source cross-platform terminal emulator that presents you with a Sci-Fi inspired look along with useful some features as well.

It was originally inspired from the DEX UI project. It is also worth noting that eDEX-UI is no longer maintained but it hasn’t been completely abandoned. You can learn more about the current status of the project here.

Even though eDEX-UI is more about the looks and the futuristic theme for a terminal, it could double up as a system monitoring tool for Linux in the future if the development resumes or if someone else forks it. How? Because it shows system stats in the sidebar while you work in the terminal.

User-friendly, colorful output
Adjusts to your terminal's width
Sort the results according to your needs
Groups & filters devices
Can conveniently output JSON

In this course, students will learn to develop complex system-level software in the C programming language while gaining an intimate understanding of the Unix operating system (and all OS that belong to this family, such as Linux, the BSDs, and even Mac OS X) and its programming environment.

Topics covered will include the user/kernel interface, fundamental concepts of Unix, user authentication, basic and advanced I/O, fileystems, signals, process relationships, and interprocess communication. Fundamental concepts of software development and maintenance on Unix systems (development and debugging tools such as "make" and "gdb") will also be covered.

Students are expected to have a good working knowledge of the C programming language, have written non-trivial programs before, and to be able to competently use a Unix system with a command-line shell interface. All coursework will be done exclusively on a Unix system from the command-line. This is not an introduction to using Unix!

You still generate a public-private key pair for each developer. However, you don’t upload the public keys to your servers.

Instead, you sign the public keys with a so-called certificate authority (CA) key which you generate before. This signing simply generates a third certificate file which you give back to the developer and they put it inside of their .ssh/ folder next to the private and public key.

On the servers, you simply tell the server the public key of your CA and the server can detect if a user has a properly signed certificate and only allows access to the developers who have such a signed certificate.

Today in some versions of Linux ls puts single quotes around file names which contain white space likely in order to have those paths easier to copy and paste, but it does so only if !isatty().

I’m not a great fan of changing a program’s well-known behaviour, specially in a case such as with GNU ls which already uses an environment variable for coloring output; it would likely have been easy to augment that for the file name quoting.

It used to be simpler to teach. (But I don’t really teach Unix beginners any more.) :-)

A load testing tool capable of performing real-time analysis, inspired by vegeta and jplot.

JuliaMono is a monospaced typeface designed for programming in the Julia Programming Language and in other text editing environments that require a wide range of specialist and technical Unicode characters.

Cursus writes your commands into an sqlite db. With cursus you can search for commands and the searched term will be highlighted if it was found.

Xonsh is Python with added shell syntax thrown in. This makes it an ideal, intuitve way to interact with your computer. You probably already know Python, and so xonsh allows you to run command line applications with out needing to learn a new, arcane syntax when ever you want to use a for-statement.

bit is an experimental modernized git CLI built on top of git that provides happy defaults and other niceties:

command and flag suggestions to help you navigate the plethora of options git provides you
autocompletion for files and branch names when using bit add or bit checkout
automatic fetch and branch fast-forwarding reducing the likelihood of merge conflicts
suggestions work with git aliases
new commands like bit sync that vastly simplify your workflow
commands from git-extras such as bit release & bit info
fully compatible with git allowing you to fallback to git if need be.
get insight into how bit works using bit --debug.

Oh my Posh enables you to use the full color set of your terminal by using colors to define and render the prompt.

This project literally makes your web browsing available COMPLETELY OFFLINE. Your browser does not even know the difference. It's literally that amazing. Yes.

Save your browsing, then switch off the net and go to http://localhost:22120 and switch mode to serve then browse what you browsed before. It all still works.

warning: if you have Chrome open, it will close it automatically when you open 22120, and relaunch it. You may lose any unsaved work.

teler was designed to be a fast, terminal-based threat analyzer. Its core idea is to quickly analyze and hunt threats in real time!

Ping, but with a graph.

Comes with the following super-powers:

Graph the ping time for multiple hosts
Graph the execution time for commands via the --cmd flag
Custom colours
Windows, Mac and Linux support

A tool to monitor I/O latency in real time. It shows disk latency in the same way as ping shows network latency.

dog is an open-source DNS client for the command-line. It has colourful output, supports the DoT and DoH protocols, and can emit JSON.

OpenSSH is the implementation of the SSH protocol. OpenSSH is recommended for remote login, making backups, remote file transfer via scp or sftp, and much more. SSH is perfect to keep confidentiality and integrity for data exchanged between two networks and systems. However, the main advantage is server authentication, through the use of public key cryptography. From time to time there are rumors about OpenSSH zero day exploit. This page shows how to secure your OpenSSH server running on a Linux or Unix-like system to improve sshd security.
