• How to install Vagrant on Ubuntu 22.04 | FOSS Linux

  Vagrant is an open-source software used to manage and generate different virtual environments using virtualization techs such as VirtualBox, VMware, and more. It simplifies the config management of virtual machines to boost productivity with the aid of provisioners. Provisioners fundamentally permits the customization of the configuration of virtual machines.

  Vagrant gives many development environments to DevOps, allowing the developers to work beyond several operating systems. One exciting feature of Vagrant is that you can install this tool on nearly all Linux distros. It is essential to know that Vagrant is a command-line generated tool.

  Also, you must ensure that you have a virtualization engine like Hyper-V, VirtualBox, or Docker setup on your system since you cannot run the Vagrant tools without virtualization software. The Vagrant plugin system also supports KVM and VMware.

• How to install TeamViewer in Ubuntu 22.04 LTS | FOSS Linux

  TeamViewer is proprietary software that permits a user to remotely access another user’s desktop, share the desktop and even facilitate file transfer between the PCs over an internet connection. It is a well-known app among helpdesk support staff and comes in handy when aiding remote users who are stuck and can also not get worthwhile assistance.

  Better yet, the program works well with all major platforms: macOS, Windows, and Linux (also in limited forms on android and iOS). Besides file transfer, TeamViewer lets you chat with its users in real-time, sync clipboard contents, and much more.

  The complexity of the application does not, however, compromise the program’s simplicity. As such, it is a pretty straightforward app as you only need to install it on both PCs required for connection, then interlink them using the unique ID and password it auto-generates. While this app’s core feature is skewed more towards the IT professionals, DevOps, and support agents, it is free for one’s use (and comes in handy for helping a frustrated friend or relative).

• How to install ThinkorSwim on Ubuntu 22.04 LTS Linux

  Thinkorswim was launched in 1999 as an options brokerage platform. However, later it was acquired by TD Ameritrade, although Thinkorswim’s brokerage services were shut down, the trading platform is still active and distributed by TD Ameritrade for its clients. Besides the trading feature, Thinkorswim users also have access to trading and analysis tools, online courses, etc.

  Unlike TradingView which can be linked to the trading accounts of many different brokers, Thinkorswim is only used by TD Ameritrade clients.

  Thinkorswim allows users to freely set alerts based on parameters of technical indicators and price movements. Meanwhile, TradingView allows users to receive only 12 different alert conditions. However

  Thinkorswim is a bit more complicated for beginners. It is confusing even for many experienced traders. However, the platform has a fairly detailed and comprehensive system of study guide documents that users can use when they need to study.

  Thinkorswim is completely free for customers, which is a big plus. For traders with TD accounts, Ameritrade has provided extensive knowledge for traders who want to learn about trading and investing.

• How to Install Puppy Linux On a USB Flash Drive - Make Tech Easier

  Puppy Linux is a family of distributions that provide a simple way to use Linux on lower-end machines. Unlike regular distros, Puppy Linux uses popular versions of existing distributions and it modifies them to run with lower system requirements.

  This allows you to install this distribution on just about any system and storage medium possible. For example, you can install and boot a working copy of the latest version of Puppy Linux on a 512MB flash drive. This article shows you how you can do just that.

• How to Show Warning Message to SSH Unauthorized Users

  SSH banner warnings are crucial when companies or organizations want to show a strict warning message to discourage unauthorized users from accessing a Linux server.

  These SSH banner warning messages are displayed just before the SSH password prompt so that unauthorized users who are about to gain access are made aware of the aftermath of doing so. Typically, these warnings are legal consequences that unauthorized users can suffer should they decide to ahead with accessing the server.

  Be cautious that a banner warning is by no means a way of blocking unauthorized users from logging in. The warning banner is simply a warning meant to warn unauthorized users from logging in. If you want to block unauthorized users from logging in, then additional SSH configurations are required.

• How to Tell If a Bash String Contains a Substring on Linux

  Sometimes in Linux scripts, you want to know if a string of text contains a specific, smaller string. There are many ways to do this. We show you some simple, reliable techniques.

  Why Is This Useful?

  Searching a string for a smaller substring is a common requirement. One example would be reading text from a file or from human input and searching the string for a specific substring so that your script can decide what to do next. It might be looking for a label or device name in a configuration file or a command string in a line of input from a user.

  Linux users are blessed with any number of utilities for manipulating text. Some are built into the Bash shell, others are provided as standalone utilities or applications. There’s a reason Unix-derived operating systems are richly served with string manipulation capabilities.

• How do I Copy a Particular File to Multiple Directories on Linux - TREND OCEANS

  Whenever I have to copy a particular file to multiple directories, I literally feel what a clunky job I have to do. Manually copying a single file to multiple locations is a total waste of time when you know you have to move this file across hundreds of directories.

  Anyway, I need to do this, so there is no way to escape from this, so let’s be brave and find the solution to overcome this hurdle in the following article.

  As you know, bare usage of cp or mv commands is not reliable for copying or moving content to multiple locations at once. However, with a little tweak, you can use the mv or cp command to move or copy files at multiple locations, which we will see in the subsequent section. Apart from that, you can also use find, tee, and usage of echo and xargs commands to achieve your desired result.

• 3 ways to install Emacs text editor on Ubuntu 22.04 LTS

  There are multiple ways to install Emacs on Ubuntu 22.04 Jammy JellyFish Linux using the command terminal and graphical user interface.

  GNU Emacs is a programmable text editor suitable for development. It is a very comprehensive and platform-independent editor that can be expanded with its own Lisp dialect (Emacs Lisp). GNU Emacs makes it easier to write source code through syntax highlighting and can be adapted by the user. Since its control is mainly based on keyboard shortcuts, it requires some training in order to be able to use all its possibilities intensively. Thanks to a large number of plugins, the editor can be used in almost all areas. There are, for example, extensions for file management, email and news, IRC, compilations, web surfing, and much more. Furthermore, it can also be used to create text documents based on LaTeX.

• Linux Fu: Eavesdropping On Serial | Hackaday

  In the old days, if you wanted to snoop on a piece of serial gear, you probably had a serial monitor or, perhaps, an attachment for your scope or logic analyzer. Today, you can get cheap logic analyzers that can do the job, but what if you want a software-only solution? Recently, I needed to do a little debugging on a USB serial port and, of course, there isn’t really anywhere to easily tie in a monitor or a logic analyzer. So I started looking for an alternate solution.

  If you recall, in a previous Linux Fu we talked about pseudoterminals which look like serial ports but actually talk to a piece of software. That might make you think: why not put a piece of monitor software between the serial port and a pty? Why not, indeed? That’s such a good idea that it has already been done. When it works, it works well. The only issue is, of course, that it doesn’t always work.

• Manage containers at the edge with Linux | Enable Sysadmin

  I often hear the question: "How do I manage containers with RHEL?" I think there's a knowledge gap here because many users never took docker run [image] beyond a laptop and into production. This is a good thing for many environments, as using an orchestration platform like the industry default Kubernetes provides almost endless capabilities and benefits.
