Whether you are handling logs, filtering outputs, validating formats, or parsing input data, regex can make your scripts significantly more powerful and efficient. This article, the first in a three-part series, […]
Continue ReadingIn today’s fast-paced software development world, keeping track of what’s happening in a project over time is critical. Teams are constantly building, updating, fixing, and deploying code. Without a structured way to mark important stages in this process, it’s easy to lose track of stable builds, crucial fixes, and key releases. That’s where Git tags […]
Continue ReadingWorking with files is one of the most fundamental and frequent tasks in Bash scripting. Whether you’re examining log files, processing configuration data, or filtering records from structured files, the ability to read content line by line is essential. This technique is particularly valuable when dealing with large files or data that needs to be […]
Continue ReadingTerraform, an open-source Infrastructure as Code (IaC) tool developed by HashiCorp, enables developers and system administrators to automate the provisioning, updating, and versioning of infrastructure. It allows users to define infrastructure using a declarative configuration language and manage the lifecycle of cloud services such as virtual machines, networking, storage, and more across a variety of […]
Continue ReadingDevOps is a modern approach to software development and IT operations that combines both disciplines into a unified process. The term itself is a combination of two words: development (Dev) and operations (Ops). At its core, DevOps is a culture and a set of practices that aim to improve collaboration, automation, and integration between software […]
Continue ReadingDocker Compose is widely acclaimed for its ability to streamline the deployment of multi-container applications. Developers use it to define services, networks, and volumes with ease, all within a single YAML configuration file.
