How to Find the List of Daemon Processes and Zombie Processes in Linux
This article will guide you to understand zombie processes and daemon processes, and help you identify processes running in the background on Linux systems. What is a Zombie Process?

Read MoreHow to Format a Hard Disk on Linux OS
In this article, we will learn how to format and configure a hard disk on Linux OS. When a new drive is installed and visible to the BIOS, it is automatically detected by the operating system. Disk drives are assigned device names beginning with hd or sd followed by a letter indicating the device order (e.g., /dev/sda, /dev/sdb). Detecting the New Hard Drive First, verify that the new drive is detected by listing all storage devices: # ls /dev/sd* /dev/sda /dev/sda1 /dev/sda2 /dev/sdb This output shows that /dev/sda is divided into two partitions (/dev/sda1 ...
Read MoreWindows in safe mode troubleshoots all system issues
Windows Safe Mode is a diagnostic startup mode that loads only essential system files and drivers, allowing users to troubleshoot and resolve system issues that prevent normal Windows operation. When computers experience problems due to faulty drivers, malware infections, or software conflicts, Safe Mode provides a minimal environment where these issues can be addressed safely. Safe Mode operates as a bare-bones version of the Windows operating system, designed to boot the system securely without problematic software interference. This stripped-down environment facilitates troubleshooting by eliminating potential conflicts and providing access to system tools needed to resolve problems. How Safe ...

Basic cat Command Usage The simplest usage of cat is to display file contents: $ cat text.txt I love tutorialspoint.com This command reads the file and displays its content to stdout (standard output) on your terminal. ...
Read MoreLearn Modern Service Management System (Systemd) on Linux
systemd is a modern system and service manager for Linux operating systems. Running as the first process on boot (PID 1), it acts as an init system that initializes and maintains userspace services, replacing traditional SysV init scripts with a more efficient service management framework. systemd provides comprehensive system initialization, service management, and system state control through its suite of tools, primarily systemctl for service control and systemd-analyze for performance analysis. Basic systemd Information To get help information about systemd, use the following command − $ systemd -h Starts up and maintains ...
Read MoreMastering Package Management system with Dpkg
Dpkg is a low-level package management tool for Debian-based Linux systems. It provides direct control over package installation, removal, configuration, and querying through command-line parameters. Unlike higher-level tools like apt, dpkg operates directly on .deb package files and maintains the package database. Every dpkg command consists of one action parameter that tells dpkg what to do, along with optional flags that modify the behavior. Dpkg is the foundation upon which other package managers are built. Getting Help To view all available dpkg options and commands − dpkg --help This displays a comprehensive list ...
