Whether you're a seasoned system administrator, a developer, or just a Linux enthusiast, having a good grasp of loop constructs in Bash can significantly elevate your ability to automate tasks and manage multiple files or processes efficiently. In this post, we'll dive into the three primary loop constructs in Bash: for, while, and until. Moreover, we'll cover how to set up Bash on your Linux system, with instructions for different package managers like apt, dnf, and zypper.
