Collection of random scripts that make my life in the Linux console way simpler.

Do not expect readability, stability, compatibility, portability, applicability, or survivability.

Most of them are just a verbatim dump of what I'm using on my system(s). Simply sharing them to give back to the community. Written in shell, bash, python, and even php.

K9s provides a terminal UI to interact with your Kubernetes clusters. The aim of this project is to make it easier to navigate, observe and manage your applications in the wild. K9s continually watches Kubernetes for changes and offers subsequent commands to interact with your observed resources.

Unified access to the best community driven cheat sheets repositories of the world.

Let's imagine for a moment that there is such a thing as an ideal cheat sheet. What should it look like? What features should it have?

Concise — It should only contain the things you need, and nothing else.
Fast — It should be possible to use it instantly.
Comprehensive — It should contain answers for every possible question.
Universal — It should be available everywhere, anytime, without any preparations.
Unobtrusive — It should not distract you from your main task.
Tutoring — It should help you to learn the subject.
Inconspicuous — It should be possible to use it completely unnoticed.

Such a thing exists! It's easy to install and there's even auto-complete.

Consistent security controls and high reliability are common expectations for any systems administrator. How do you deliver both on a network with thousands of servers supporting thousands of engineers? Most off-the-shelf solutions require a compromise in at least one of these areas — and we refused to accept this.

Most systems administrators use the industry-standard Secure Shell (SSH) for accessing systems, and yet many of its special features are not widely leveraged. At Facebook, we take advantage of those features to use SSH in a way that is reliable, secure, and manageable. SSH, more specifically OpenSSH, has a great way to provide both the security and reliability we require: signed certificates with principals.

Automatically show a cheat sheet or notes for any command focused in tmux. e.i. Show vim, zsh, tmux notes/key-combos in a pane when using them.

If you want your list to be included on awesome, try to only include actual awesome stuff in your list. After all, it's a curation, not a collection.

But what is awesome?
Only awesome is awesome
Research if the stuff you're including is actually awesome. Only put stuff on the list that you or another contributor can personally recommend. You should rather leave stuff out than include too much.

Multiplayer Tron in your terminal. Just run the command below and you'll be playing in seconds

OProfile has been around for decades, and for some time was the workhorse of performance profiling on Linux®-based systems, and can serve the same role today. However, OProfile is not included in Red Hat Enterprise Linux (RHEL) 8 beta, and so it may be prudent for OProfile users to start considering alternative tools. Analogous projects which compare very favorably to OProfile in features, ease-of-use, and vitality of the community do exist. One such project is the Linux perf command. Until recently, when compared to OProfile, perf had some drawbacks such as lack of support for Java™ just-in-time (JIT) compiled programs and hardware event mnemonics, but these have been addressed in recent releases. This tutorial offers current OProfile users a roadmap for transitioning from OProfile to perf.

lab interacts with repositories on GitLab, including creating/editing merge requests, issues, milestones, snippets and CI pipelines.

The development team has focused on keeping lab a simple and intuitive command line interface for commands provided in the GitLab API. lab's aim is to provide GitLab users an experience similar to the GitLab WebUI with respect to errors and messages.

If you do a significant amount of programming, you'll probably end up with build artifacts scattered about. sn is a tool to help you find those artifacts.

sn is also a replacement for du. It has nicer output, saner commands and defaults, and it even runs faster on big directories thanks to multithreading.

I'm taking a look at twelve "obscure" window managers.

systemd is, to put it mildly, controversial. Depending on who you ask it's either a complete violation of the UNIX philosophy, a bloated pile of bugs, a complete violation of the elegant simplicity it replaced or, it most cases, some or all of the above.

So why have so many Linux distributions taken to it? Is it as bad as people say? Are the BSD projects right to be avoiding it?

Let's look into the history of UNIX userland bootstrapping and the factors that lead to the creation of systemd, why it's turned out the way it has, and what there is to be learned from it.

Clickbaity title ahoy!

In the linux world they can all look the same from the point of view of the user at the keyboard. The differences are in how they interact with each other.

The shell is the program which actually processes commands and returns output. Most shells also manage foreground and background processes, command history and command line editing. These features (and many more) are standard in bash, the most common shell in modern linux systems.

A terminal refers to a wrapper program which runs a shell. Decades ago, this was a physical device consisting of little more than a monitor and keyboard. As unix/linux systems added better multiprocessing and windowing systems, this terminal concept was abstracted into software. Now you have programs such as Gnome Terminal which launches a window in a Gnome windowing environment which will run a shell into which you can enter commands.

The console is a special sort of terminal. Historically, the console was a single keyboard and monitor plugged into a dedicated serial console port on a computer used for direct communication at a low level with the operating system. Modern linux systems provide virtual consoles. These are accessed through key combinations (e.g. Alt+F1 or Ctrl+Alt+F1; the function key numbers different consoles) which are handled at low levels of the linux operating system -- this means that there is no special service which needs to be installed and configured to run. Interacting with the console is also done using a shell program.

Ever wondered whether htop could be used to render the graphics of cult video games? I know I have. In order to quench our curiosity and for your viewing pleasure, I created doom-htop

Sixty years ago today, IBM announced the System/360, a line of computers that took over the computer industry. The big idea was that all the systems were compatible and supported all applications (a 360° range from business to scientific). 1/9

The new "Simple standalone #SSH Agent for #OpenPGP cards" (https://crates.io/crates/openpgp-card-ssh-agent) is now available as a package for #Arch Linux, by the way :arch: 😏

This agent offers a frictionless UX when using ssh with keys that are stored on OpenPGP card devices: No more ongoing PIN entry required! 🚀

@dvzrv has once again done amazing packaging and documentation work! 🥳 Thank you 😃

See https://wiki.archlinux.org/title/SSH_keys#OpenPGP_card_ssh-agent for details.

I hate apps that don't allow you to copy text from a comment field. It gives you a taste of the world without Larry Tesler and Tim Mott, and it's not a magnificent one

[Note: Tesler worked at Xerox PARC, Apple, Amazon, and Yahoo!. While at PARC, Tesler's work included Smalltalk, the first dynamic object-oriented programming language, and Gypsy, the first word processor with a graphical user interface (GUI) for the Xerox Alto. During this, along with colleague Tim Mott, Tesler developed the idea of copy and paste functionality and the idea of modeless software. ]

Let’s say I want to keep the latest version of each file as they are replaced or removed; essentially I want a “trash can”-like behavior. For this, I create the following script and store it as /Users/jb/bin/onlylatest.sh (i.e. the bin directory in my home directory):
