How can you view the content of a text file named "example.txt" page by page in Linux?

The choice "less example.txt" is the correct answer because the less command allows users to view the contents of a text file in a paginated manner, enabling them to scroll both forward and backward through the text. This command is particularly useful for large files as it does not load the entirety of the file into memory, instead allowing users to navigate through the content smoothly using keyboard shortcuts.

While both more example.txt and view example.txt also allow for viewing file content page by page, less is generally preferred due to its advanced navigation capabilities. The more command primarily allows forward navigation, whereas less facilitates both forward and backward scrolling, making it more versatile.

The command cat example.txt, on the other hand, outputs the entire content of the file to the terminal without pagination. This means if the file is larger than the terminal screen, the text will scroll past quickly, making it difficult to read. Thus, it does not provide the desired functionality of viewing the file content page by page.
