The ls command in Unix-like operating systems is a powerful tool for listing files and directories in a directory. One of the convenient features of the ls command is the ability to customize the way it displays information. By default, ls lists entries in columns, making it easy to read in a tabular format. However, there might be scenarios where you prefer a different layout, such as listing entries by lines. In this guide, we'll explore the ls option that allows you to achieve this.
