To create a bootable USB drive from an ISO file in Linux, we find it useful when installing a new operating system or running a live environment without affecting my existing system. It's also an excellent option when my computer lacks a CD/DVD drive, as USB drives are more common and easier to use. To start the process, we use the "lsblk" command to find the device name of the USB drive and then download the ISO file. we then mount the ISO file and use the mount and dd commands to copy its contents to the USB drive. When ... Read More

The robust command line interface (CLI) of Linux is renowned for enabling users to complete tasks quickly and effectively. Copying file content directly from the terminal is one of the many tasks Linux users frequently carry out. This article explores the subtleties of copying file content in Linux, explaining various approaches and providing detailed step-by-step instructions. Readers will gain a profound understanding of each strategy by carefully examining these approaches. Let's set out on this instructive journey to discover the complexities of copying file content in Linux. Method 1: Using the 'cat' Command In Linux, the 'cat' command is a ... Read More

In today's digital age, images play a vital role in websites and various digital projects. But, the larger the image size, the longer it takes to load, leading to a poor user experience. You probably want to know the solution to this. Fortunately, Google has developed the WebP image format, which offers superior compression and quality compared to traditional image formats like JPEG and PNG. In this article, we will delve into how you can convert images to the WebP format on Linux using the WebP tools. By converting your images to WebP format, you can significantly reduce their file ...

As Linux users and administrators, we are responsible for managing services on remote Linux servers, which could include web servers like Apache or Nginx, or database servers like MySQL or PostgreSQL. To effectively manage these services, we need to have a strong understanding of the underlying system and service manager for Linux - systemd. Systemd is a robust and feature-rich system and service manager designed for Linux-based operating systems. It takes care of managing the initialization and termination of services, tracks system processes, and oversees system resources. It is widely acquired as the default system and service manager in many ... Read More

In the realm of operating systems, process scheduling plays a vital role in achieving efficient task execution. A key aspect of process scheduling is the management of Process Control Blocks (PCBs) and the utilization of various queueing techniques. This article explores the significance of PCBs and queueing in the process scheduler, highlighting their role in optimizing system performance. Process Control Blocks (PCBs) Definition and Purpose The successful operation of an operating system rests on its ability to use the data structure known as a Process Control Block (PCB) effectively. PCBs allow for efficient storage and management of process related information. ... Read More

Process scheduling plays a crucial role in the efficient functioning of operating systems. Within the realm of process scheduling, understanding job and process status is essential for effective management and optimization. In this article, we will delve into the concept of process scheduler, explore job and process status, and examine their significance in operating systems. As computers execute multiple tasks simultaneously, a process scheduler ensures fair allocation of system resources and efficient execution of processes. Job and process status are integral components of the process scheduling mechanism, providing insights into the progress and state of running processes. Understanding Process Scheduler ... Read More

The proper management and control of processes are integral components of efficient system functionality. In this piece. We will examine two essential facets: the process table and Process Control Block (PCB). We will delve into their definitions, purposes, and significance in operating systems. The Process Table Definition and Purpose Operating systems utilize what's known as a "process table" as means to accurately monitor active processes within their infrastructure. Such tables are responsible for compiling vital information concerning every single running program/system component under supervision from an OS. Thus keeping an exhaustive inventory about these details aids in controlling/dispatching them smoothly ... Read More

If you are a Linux user and wish to connect to a Wi-Fi network from a terminal. Although it may seem scary, it is actually a simple process using the Nmcli command. In this article, I will introduce you to the steps of connecting Wi-Fi from a Linux terminal using Nmcli commands in a simple and easy-to-understand way. So let’s get started! First, if we want to check the name of our network device we can simply do that by running the following command − $ iw dev You’ll get the output kind of this by running the command − ... Read More

Multitasking underscores the versatility inherent in modern-day OSes that empowers computers with concurrent task handling capabilities. Process-based or thread-based multitasking represents efficient resource consumption strategies that positively impact overall system performance levels.
