exFAT stands for Extensible File Allocation Table and is a format made by Microsoft for use on devices like USB flash drives. In general, you do not hear a lot about exFAT these days, but it remains a viable format that is compatible with Windows, MacOS, and Linux, so it is a good choice for a flash drive that you plan on using with a variety of different systems. Some manufacturers even use exFAT as the default format for their SD cards or other products.

How to Check Kubernetes Version on Linux
Checking the installed version of Kubernetes is an important part of system administration, since it will allow you to keep on top of the latest updates and security patches that are released for your software. It is also important to ensure that your various Kubernetes components are updated alongside each other, as much variance in the version number could cause problems.
How to Disable Swap in Linux for Kubernetes
Part of the official requirements for Kubernetes is to disable swap space completely before attempting to launch Kubernetes. In some recent patch notes, Kubernetes has begun implementing support for swap space in some scenarios, but it is not fully supported. The official reason for not supporting swap space is because it is hard to predict how a pod might utilize memory when swap is enabled.
How to check what shell I’m using on Linux
The shell on a Linux system is the layer that interprets the commands being executed by the user, and translates them into a language that the operating system can understand. The Bash shell is the default one in Linux, and typically what all users become familiar with first. But there are a lot of other shells that can be used, too; like sh, zsh, ksh, csh, and tcsh, to name a few.
How to paste into terminal
Linux users that are new to using the command line terminal will quickly realize that the typical and well known Ctrl + C
and Ctrl + V
keyboard shortcuts do not work for copying and pasting. Instead, Ctrl + C
will interrupt a running command, so users must quickly make new habits and learn the proper way to copy and paste into the terminal. In this tutorial, we will show you all the ways to paste your clipboard into the terminal on a Linux system. We will also go over a few ceveats that you may need to know.
How to scroll up in terminal on Linux
The command line is the most powerful feature of a Linux system, as it allows users to quickly accomplish tasks that would usually take longer using a GUI. In order to be more efficient with using the command line terminal, it is important to know how to navigate around it more quickly. In this tutorial, we will show you how to scroll up in the terminal on a Linux system. This will work for systems that are not using a GUI, such as when logged into an SSH session.
How to switch user on Linux
Linux is a multi user operating system, meaning that it supports having multiple simultaneous user accounts. Some Linux systems may have a few different accounts, and others could have hundreds, depending on the purpose of the system. Switching between user accounts is a common task for Linux administrators who are in charge of user account management, as it allows them to test permissions or troubleshoot problems.
How to Install kubectl Linux Binary
The kubectl command is an essential part of Kubernetes, and is used to single handedly manage the entire cluster. It provides an interface for administrators to get information about their Kubernetes cluster, and manage the cluster through deploying applications and services, scaling systems, performing updates, and much more. On a Linux system, there are several ways to install the kubectl
binary and to keep it up to date.
How to Use Kubernetes Namespaces
In order to have a logical separation for different groups of resources, Kubernetes gives us the namespaces feature. It is also convenient when you have a big environment that is managed by multiple users or teams, and each one needs their own “space” for the resources that they are assigned to manage and administer. This is a much better solution than creating numerous Kubernetes clusters just to facilitate different groups of services or deployments, and to isolate teams to their own space.
How to Use Scale Command in Kubernetes
One of the most important features of Kubernetes is the ability to easily scale our containerized applications. This allows administrators to deal with increased traffic by adding more replicas that can handle the uptick in activity. Kubernetes can handle the load intelligently by distributing the work evenly to pods in the cluster, ensuring that none of them become overwhelmed.
How to Perform Rolling Update in Kubernetes
Kubernetes offers administrators a way to update our hosted services and containerized applications without having any downtime. This is accomplished through rolling updates, which will update the application in one replica at a time, so that users accessing the service can continue without interruption. After a little time, every replica will have undergone the issued update.
How to mount USB drive in Linux
In this tutorial, we explain how to mount USB drives in a Linux system using terminal and shell command line. This allows you to mount a USB drive of any file system, to some mount point on your system. If you are using desktop manager, you will most likely be able to use it to mount USB drive for you.
