What function does the 'less' command serve in Linux?

• A. Display text one screen at a time
• B. Concatenate multiple files
• C. Search text within a file
• D. Count the number of words in a file

Answer: (A)

The 'less' command in Linux is primarily used to display text one screen at a time, allowing users to scroll through the displayed content. It is a pager that lets you view and navigate through the output easily, especially for long files that don't fit on a single screen. This capability enables users to efficiently browse text, pausing and resuming as needed, making it a valuable tool for examining files without overwhelming the user with excessive information at once. The command allows for both forward and backward scrolling, enhancing the user's ability to comprehend and navigate through the text easily. The other functions mentioned do not accurately represent the purpose of the 'less' command; for instance, concatenating files, searching text, or counting words are handled by different commands (such as 'cat', 'grep', and 'wc' respectively) that serve those specific tasks.
