Which command would you use to display and scroll through file content interactively?

The command that enables you to display and scroll through file content interactively is more. When you use the more command, it presents the content of a file page by page, allowing the user to scroll through it. This is particularly useful for larger files, as it prevents the terminal from being flooded with text, letting you read the content at your own pace. You can navigate through the content using keys like the spacebar to move forward one page or the Enter key to move down one line.

In contrast, the tail command primarily displays the last part of a file and does not facilitate interactive scrolling through the entire content. The scroll option is not a valid command in Unix/Linux systems, and the cat command outputs the entire content of a file directly to the terminal without any paging capability, making it unsuitable for interactive viewing of larger files. Thus, more is designed specifically for the purpose described in the question.
