Read MoreWhat languages have been used to write Windows, Mac OS and Linux OS?
An operating system serves as the backbone of any computing system, managing hardware resources and providing essential services. The three most widely used operating systems — Windows, macOS, and Linux — share fundamental concepts while implementing them using different programming languages and architectural approaches. These operating systems differ not only in their user interfaces and file management systems but also in the programming languages and technology stacks used for their development. Understanding the languages behind these systems provides insight into their design philosophy and performance characteristics. Linux Operating System Linus Torvalds, the creator of Linux, explained his ...
Read MoreCommand chaining: Inline or Already running process
Command chaining allows you to run multiple commands sequentially in Linux. This is useful when you need to execute a series of related operations, such as downloading a file, extracting it, and then cleaning up. Command chaining can be done inline when starting commands or applied to processes that are already running. Inline Command Chaining Bash provides several operators for chaining commands together. The general syntax is: ... Common Chaining Operators ; (semicolon) − Executes commands sequentially regardless of success or failure & (ampersand) − Runs the ...

Read MoreBest Debian-based Linux Distributions
Debian-based Linux distributions are built on the foundation of Debian GNU/Linux, inheriting its stability, extensive package management system, and robust architecture. These distributions offer users access to thousands of pre-compiled software packages through the APT (Advanced Package Tool) system, making software installation and maintenance straightforward. Ubuntu Ubuntu is the most popular Debian-based distribution, developed by Canonical Ltd. It focuses on ease of use, regular release cycles, and comprehensive hardware support. Ubuntu releases new versions every six months, with Long Term Support (LTS) versions every two years that receive five years of security updates. $ lsb_release -a No ...
Read MoreWhat Linux utility for sorting processes by network usage?
Linux provides the famous top command utility that displays information about running processes, including their time, process IDs, CPU usage, and much more. However, the top command does not sort processes by network usage, and the display order changes frequently based on CPU consumption. When you need to monitor which processes are consuming the most network bandwidth, you need a specialized tool. NetHogs is the ideal Linux utility for sorting and monitoring processes by their network usage in real-time. What is NetHogs? NetHogs is a command-line network monitoring tool that displays real-time network traffic bandwidth usage for ...
Read MoreWhat are the process states in Windows and Linux?
A process is not only a program under execution but it is the active state of the program when it is executing and it has its own Process Control Block (PCB). A process requires various resources like memory, CPU, hard disk, and Input/Output devices to function properly.

Read MoreHow to Get the Path of a Linux Command?
A Linux command that you run from a terminal window can be built-in (a part of the system), a function (an application that runs when you enter certain commands), an alias (another name for a command), or an external executable (a program that you download). You can use the which, command, whereis, whatis, and type tools to determine what each one is and where they are located. We will look at the which, command, type, and whereis commands as they are usually found in most Linux-based operating systems. PATH Environment Variable Before we get into the details ...
Read MoreThe Meaning of IFS in Bash Scripting on Linux
In Bash scripts on Linux, the "IFS" (Internal Field Separator) variable plays an important role in controlling how fields in a string are separated. IFS defaults to a space, tab, and newline character, which means that, by default, fields in a string are separated by any combination of these characters. However, the IFS value can be changed to meet the specific needs of a script. In this article, we will explore the meaning of IFS in Bash scripting and how it can be used in various scenarios. What is IFS? IFS is a special variable in Bash which ...
