How to See Hidden Files in Linux Terminal

Introduction

Linux is a powerful operating system that allows users to manage files and directories with ease. However, one of the most useful features of Linux is the ability to see hidden files. In this article, we will explore how to see hidden files in Linux terminal.

Why See Hidden Files?

Before we dive into the solution, let’s understand why we need to see hidden files. Hidden files are files that start with a dot (.) or a tilde (~), and they are not visible by default. These files are usually created by the system to store temporary files, logs, and other system-related data. By seeing hidden files, we can:

• Identify system-related issues: Hidden files can indicate system-related problems, such as disk space issues, file system corruption, or system crashes.
• Manage system files: We can use hidden files to manage system files, such as system logs, configuration files, and other system-related data.
• Optimize system performance: By identifying hidden files, we can optimize system performance by deleting unnecessary files and freeing up disk space.
