When managing a Linux system, you may frequently come across timestamps recorded in Coordinated Universal Time (UTC). Understanding and converting these timestamps to your local time can be essential, particularly when troubleshooting system events or running time-specific commands. This article will provide you a comprehensive guide to converting UTC date and time to local time in Linux, accompanied by practical examples. Understanding Timezones in Linux In Linux, timezones are typically defined in the /etc/localtime file. This file is often a symbolic link to a file located in the /usr/share/zoneinfo directory that corresponds to your timezone. You can view the timezone…

In the wide array of commands offered by Git, a popular version control system, git restore stands as a crucial command for developers worldwide.

It is seen as an intuitive and safer alternative to other commands, such as git checkout and git reset. Understanding Git Restore The git restore command is a versatile tool that allows developers to restore files to a specific state. This means you can undo the changes made to files in…

Since its creation, Git has become an essential tool for programmers worldwide. It aids in source code management, collaborative development, and version control, among other things. Recently, Git introduced a new command, git switch, which is an alternative to git checkout and provides a more intuitive way to switch between branches or restore working tree files. This article will explore the `git switch` command in detail, discuss its functionality, and provide practical examples to help you understand and use this command effectively. 1. Understanding Git Switch Introduced in Git version 2.23.0, the git switch command is designed to simplify the…

Git is an industry-standard distributed version control system used for software development and other version control tasks. It facilitates collaboration, allowing multiple contributors to work on a project concurrently without overriding each other’s changes. Among the numerous commands in Git, git checkout and git switch are two that play a critical role in navigating through different branches of a repository. Understanding the similarities and differences between these commands, as well as their appropriate uses, is vital for effective Git operation. `git switch` is a relatively new command, introduced in Git 2.23.0, designed to simplify certain operations that were traditionally performed…

The Squid proxy server is an open-source, high-performance proxy caching server for web clients that supports FTP, HTTPS, and HTTP data objects. It is mainly designed to accelerate content delivery by caching frequently requested data and freeing bandwidth. A lesser-known feature of Squid, however, is the ability to restrict access to certain websites or to block specific keywords. This article will guide you through the steps needed to block specific keywords using Squid proxy server. Before we proceed, please note that you should have root or sudo user access to the Squid server to configure these settings. Step 1: Install…

The Simple Mail Transfer Protocol (SMTP) is a communication protocol used in the internet mail system. SMTP is responsible for sending, receiving, and relaying outbound mail between email senders and receivers. As a core component of the internet, SMTP is an application layer protocol that works closely with the Mail Transfer Agent (MTA) to transfer email data to its correct destination. This article delves into the origins, functionality, and significance of SMTP. Understanding the Simple Mail Transfer Protocol SMTP was first defined in RFC 821 in 1982 by Jon Postel, as a part of the early establishment of the Internet.…

In the realm of software development, version control is paramount.
