In this article, we will cover some basic usage of the cat command, which is the command that is used the most frequently in Linux, and tac, which is the reverse of the cat command and prints files in reverse order. We will illustrate these concepts with some examples from real life.
How Cat Command Is Used
One of the most popular commands in *nix operating systems is called "cat," which is an acronym for "concatenate." The most fundamental application of the command is to read files and output their contents to the standard output, which simply means to show the contents of files on your computer's terminal.
#cat micro.txt
In addition, the cat command can be used to read or combine the contents of multiple files into a single output, which can then be displayed on a monitor, as shown in the examples that follow.
#cat micro1 micro2 micro3
Utilizing the ">" Linux redirection operator enables the command to also be used to combine multiple files into a single file that contains all of the combined contents of the individual files.
#cat micro1 micro2 micro3 > micro-all
#cat micro-all
The following syntax allows you to append the contents of a new file to the end of the file-all.txt document by making use of the append redirector.
#cat micro4 >> micro-all
#cat micro4
#cat micro4 >> micro-all
#cat micro-all
With the cat command, you can copy a file's contents to a new file. Any name can be given to the new file. Copy the file from where it is now to the /tmp/ directory, for example.
#cat micro1 >> /mnt/micro1
#cd /mnt/
#ls
One of the less common uses of the cat command is to generate a new file using the syntax shown below. After you have finished making changes to the file, press CTRL+D to save and close the modified file.
#cat > new_file.txt
Applying the -n switch to your command line will cause all output lines of a file, including blank lines, to be numbered.
# cat -n micro-all
Use the -b switch to show only the number of each line that isn't empty.v
#cat -b micro-all
Discover How to Use the Tac Command
On the other hand, the tac command is one that is not as well known and is utilised only occasionally in *nix systems. This command prints each line of a file to your machine's standard output, beginning with the line at the bottom of the file and working its way up to the line at the top. Tac is practically the reverse version of the cat command, which is also spelled backwards.
#tac micro-all
The -s switch, which separates the contents of the file based on a string or a keyword from the file, is one of the most important options that the command has to offer. It is represented by the asterisk (*).
#tac micro-all --separator "two"
The second and most important use of the tac command is that it can be of great assistance when trying to debug log files by inverting the chronological order of the contents of the log.
#tac /var/log/messages
And if you want the final lines displayed
#tail /var/log/messages | tac
Similar to the cat command, tac is very useful for manipulating text files, but it should be avoided when dealing with other types of files, particularly binary files and files in which the first line specifies the name of the programme that will execute the file.

date: "2023-04-26"
As businesses move towards cloud computing, serverless computing has become increasingly popular. It allows organizations to focus on the core business logic without worrying about the underlying infrastructure. But what exactly is serverless computing, and how does it work?
In this article, we will provide an introduction to serverless computing, its benefits, and how it differs from traditional server-based computing.
What is serverless computing?
Serverless computing is a cloud-based model that allows developers to run and scale applications without having to manage servers or infrastructure. It is a fully managed service where the cloud provider manages the infrastructure and automatically scales it up or down as required. With serverless computing, you only pay for what you use, making it a cost-effective solution.
How does serverless computing work?
In serverless computing, a cloud provider such as Amazon Web Services (AWS) or Microsoft Azure runs the server infrastructure on behalf of the customer. Developers write code in the form of functions and upload it to the cloud provider. These functions are then executed on the provider's infrastructure, triggered by events such as a user uploading a file or a customer placing an order. The cloud provider automatically allocates resources to run the function and scales it up or down as required.
Benefits of serverless computing
Serverless computing offers several benefits to businesses, including:
Cost-effectiveness: With serverless computing, you only pay for what you use, making it a cost-effective solution.
Scalability: Serverless computing automatically scales up or down based on the demand, ensuring that the application is always available to the end-users.
High availability: Serverless computing ensures high availability by automatically replicating the application across multiple data centers.
Increased productivity: Serverless computing allows developers to focus on writing code rather than managing infrastructure.
Differences between serverless computing and traditional server-based computing
In traditional server-based computing, the organization manages the servers and infrastructure, including the operating system, patches, and updates. The application runs continuously on the server, and the organization pays for the server, regardless of whether the application is being used or not. In serverless computing, the cloud provider manages the infrastructure, and the application runs only when triggered by an event. The organization pays only for the resources used during the execution of the function.
Conclusion
Serverless computing is a powerful cloud-based model that offers several benefits to businesses, including cost-effectiveness, scalability, and high availability. It differs significantly from traditional server-based computing, as it allows organizations to focus on the core business logic without worrying about the underlying infrastructure.

Deploying and Managing a Cluster on Utho Kubernetes Engine (UKE)
In this tutorial we will learn how you can deploy and manage a Cluster on Utho Kubernetes Engine (UKE). The Utho Kubernetes Engine (UKE) is a fully-managed container orchestration engine for deploying and managing containerized applications and workloads. UKE combines Utho’s ease of use and simple pricing with the infrastructure efficiency of Kubernetes. When you deploy an UKE cluster, you receive a Kubernetes Master at no additional cost; you only pay for the Utho's (worker nodes), load balancers. Your UKE cluster’s Master node runs the Kubernetes control plane processes – including the API, scheduler, and resource controllers.
Additional UKE features:
etcd Backups: A snapshot of your cluster’s metadata is backed up continuously, so your cluster is automatically restored in the event of a failure.

Launch a shell session at the terminal and add the location of your kubeconfig file to the $KUBECONFIG environment variable. The kubeconfig file can be found in the Downloads folder, as shown in the sample command, but you will need to modify this line to reflect the location of the Downloads folder on your own computer:
export KUBECONFIG=~/Downloads/kubeconfig.yaml
You may look at the nodes that make up your cluster using kubectl.
kubectl get nodes
output of the command
Your cluster is now prepared, and you can start managing it with kubectl. For further details on kubectl usage, refer to the Kubernetes guide titled "Overview of kubectl."
Use the config get-contexts command for kubectl to acquire a list of the available cluster contexts:
kubectl config get-contexts
If the asterisk in the current column does not indicate that your context is already selected, you can switch to it with the config use-context command. Please supply the full name of the cluster, including the authorised user and the cluster itself:
kubectl config use-context Utho-k8s-ctx
Output:
Switched to context "Utho-k8s-ctx".
You are now ready to use kubectl to talk to your cluster. By getting a list of Pods, you can test how well you can talk to the cluster. To see all pods running in all namespaces, use the get pods command with the -A flag:
kubectl get pods -A
all node of cluster
Modify a Cluster’s Node Pools
You can use the Utho Cloud Manager to modify a cluster’s existing node pools by adding or removing nodes. You can also recycle your node pools to replace all of their nodes with new ones that are upgraded to the most recent patch of your cluster’s Kubernetes version, or remove entire node pools from your cluster.
The details page of your Cluster
Step 1: Click the menu in the sidebar that says "Kubernetes." When you go to the Kubernetes listing page, all of your clusters are shown.
Dashboard of Mirohost Panel
Step 2: Select the cluster's manage button that you want to change. The information page for the Kubernetes cluster displays.
Manage section of K8s
Scale a Node Pool
Step 1: Go to the cluster's information page and click the "add a node pool" option to the right that shows the node pools if you want to add a new node pool to your cluster.
Scale a cluster
Step 2: Choose the hardware resources that you want to add to your new Node Pool from the menus that appear in the new window that just appeared. To add or remove a node from a node pool one at a time, choose the plus (+) and minus (-) buttons that are located to the right of each plan. Select "Add Pool" when you are pleased with the amount of nodes that are included inside a node pool before incorporating it into your setup. After you have deployed your cluster, you always have the option to alter your Node Pool if you later determine that you need a different quantity of hardware resources.
Configuration of nodes
Edit or Remove Existing Node Pools
Step 1: On the Node Pools portion of the page that displays information about your cluster, click the Scale Pool option that is shown in the top-right corner of each item.
Scale option of nodes
Step 2: After clicking on the Scale Pool, you will see the below screen. Here, just decrease the Node Count to your desired number and then clink on update button.
Similarly, if you want to delete any Node Pool, you just need to put Node Count to 0 and then click on update
Add or delete the node
Caution
The removal of nodes is an inevitable consequence of reducing the size of a node pool. Any local storage that was previously present on deleted nodes will be removed, including "hostPath" and "emptyDir" volumes, as well as "local" PersistentVolumes.
Delete a Cluster
Using the Utho Kubernetes Manager, you have the ability to remove a whole cluster. After they have been implemented, these adjustments are irreversible.
Step 1: To access Kubernetes, use the link located in the sidebar. You will then be brought to the Kubernetes listing page, where each of your clusters will be shown in turn.
Dashboard of k8s
Step 2: Choose Manage Options next to the cluster you want to remove
Manage section of Kubernetes
Step 3: Here, click on Destroy option.
Destroy the cluster
You will need a confirmation string to remove the Cluster. Enter the precise string, then confirm by clicking the Delete button.
Delete the cluster
After deletion, The Kubernetes listing page will load, and when it does, you won't be able to find the cluster that you just destroyed.
Hopefully, now you have the understanding of how to deploy and manage a Cluster on Utho Kubernetes Engine (UKE)
If you're looking for a web hosting solution that provides better performance, security, and scalability than shared hosting, you may want to consider VPS hosting. In this beginner's guide, we'll explain what VPS hosting is, its benefits, and how to choose the right provider.
What is VPS Hosting?
VPS hosting stands for Virtual Private Server hosting. It uses virtualization technology to create a virtual server, which runs its own copy of an operating system. Each virtual server has its own set of dedicated resources, such as CPU, RAM, and storage, which are isolated from other virtual servers on the same physical server.
Benefits of VPS Hosting
Improved Performance: VPS hosting provides dedicated resources, which means that your website can handle higher traffic volumes and perform better than on shared hosting.
Increased Security: With VPS hosting, you're less vulnerable to security breaches that could affect other websites on the same server, as you have your own isolated environment.
Scalability: VPS hosting allows you to easily scale your resources up or down, depending on your website's needs, without the need to migrate to a different hosting provider.
Customization: VPS hosting gives you more control over your hosting environment, allowing you to install your own software and configure your server to meet your specific needs.
How to Choose the Right VPS Hosting Provider
Choosing the right VPS hosting provider is crucial for your website's success. Here are some factors to consider:
Performance: Look for a VPS hosting provider with fast server performance and reliable uptime.
Scalability: Make sure that the provider offers easy scalability, so you can increase your resources as your website grows.
Support: Choose a provider with excellent customer support, available 24/7, and knowledgeable staff to help you with any issues.
Security: Look for a provider that offers robust security features, such as firewalls and DDoS protection.
Price: Consider the provider's pricing, ensuring it fits within your budget and provides good value for money.
