Introduction

When working with Linux commands, you may have come across the -y option, often used in conjunction with package managers like dnf, yum, or apt. However, the meaning and purpose of this option are not always clear. In this article, we will delve into the world of Linux options and explore what the -y flag means in various Linux commands.

What is the -y Option?

The -y option is a shorthand for the word "yes." It is used to automatically answer "yes" to any prompts that may arise during the execution of a command. This option is commonly used with package managers to install or update software without requiring user confirmation.

Example: dnf -y install samba
