How can you view a file’s content page by page?

• A. cat filename
• B. less filename
• C. more filename
• D. view filename

Answer: (B)

Viewing a file's content page by page is commonly achieved using the command `less`. This command allows users to scroll through the content of a file in an interactive manner, making it especially useful for large files. With `less`, you can move both forward and backward through the content, search for specific strings, and navigate using various key commands. This flexibility is one of the key advantages of `less` compared to other commands that display file content. The command essentially presents the file in a viewport, allowing you to read it in chunks rather than loading the entire content at once, which improves usability and efficiency when dealing with extensive texts. You can exit `less` by pressing 'q', which returns you to the command prompt without having to load the entire file into memory first. While other commands like `more` and `view` have similar functionalities, they may not offer the same level of interactivity or features that `less` does, which further emphasizes why `less` is the preferred choice for paging through files in a Linux environment.
