Read MoreMimic the Linux adduser command in C
The adduser command in Linux is used to add new user accounts on Unix-like operating systems. System administrators frequently use it to create new users with predetermined usernames, passwords, and other user-related information. This article demonstrates how to mimic this functionality using C programming and system calls. System Calls Overview System calls allow software to communicate with the operating system kernel, which manages system resources and provides services to user-level programs. In C programming, system calls provide access to OS features including file I/O, process management, and network connectivity. Essential System Calls open − Opens or ...
Read Moremindepth and maxdepth in Linux find() command for limiting search to a specific directory
The find command in Linux is used to search for files and directories within a directory structure. The mindepth and maxdepth options allow you to control the search depth, limiting results to specific directory levels. mindepth specifies the minimum depth level from which the search should start, while maxdepth defines the maximum depth level the search should reach. These options help you target specific areas within complex directory hierarchies. Understanding Depth Levels Maxdepth − Limits how deep the search goes into subdirectories. A depth of 0 means only the starting directory itself, 1 includes immediate subdirectories, and so ...
Read MoreMove cmd command
The move command in Microsoft Windows Command Prompt is a powerful utility for relocating files and folders from one location to another. This built-in command provides an efficient way to organize and manage your file system directly from the command line interface. The basic syntax of the move command follows this pattern: the command itself, followed by the source file or directory path, and then the destination path. When executed, it transfers the specified file or folder to the new location, removing it from the original position. How It Works The move command operates by transferring files ...
Read MoreCopy Linux Binaries From One Linux System to Another using Exodus?
Exodus is a powerful tool that allows you to export and import software packages, including binaries and their dependencies, from one Linux system to another. This eliminates the need for complex manual installation procedures and ensures that all required dependencies are properly transferred. Transferring Linux binaries from one system to another can be challenging, especially when dealing with multiple machines or complex dependency chains. Exodus simplifies this process by creating portable bundles that include both the binary and its runtime environment. Installing Exodus Exodus is typically not included in most Linux distributions by default, so you need ...
Read MoreCreating dialog boxes with the Dialog Tool in Linux
The Dialog tool is a command-line utility in Linux that allows developers to create interactive dialog boxes within shell scripts. These dialog boxes provide a user-friendly interface for displaying information, receiving input, and making selections, significantly enhancing the usability of command-line applications. Dialog boxes serve as an excellent bridge between the command line and graphical user interfaces, offering a text-based visual interaction that is both accessible and functional. This makes them particularly valuable for system administration scripts and user-interactive applications. Installing Dialog Tool Before creating dialog boxes, ensure that the Dialog tool is installed on your Linux ...
Read MoreCRLFuzz – A Linux Tool to Scan CRLF Vulnerability Written in Go
CRLFuzz is a powerful Linux tool written in Go that scans for CRLF (Carriage Return Line Feed) vulnerabilities in web applications. CRLF vulnerabilities occur when applications mishandle line termination characters, potentially leading to HTTP response splitting, cross-site scripting (XSS), and session hijacking attacks. This tutorial covers the installation process, demonstrates CRLFuzz usage with various command-line options, and explains how to effectively identify CRLF vulnerabilities to strengthen web application security. What are CRLF Vulnerabilities CRLF vulnerabilities arise when user input containing carriage return (\r) and line feed () characters is not properly sanitized. Attackers can exploit this to ...
