What command would you use to view the last 10 lines of a file?

• A. cat
• B. tail
• C. head
• D. more

Answer: (B)

The command used to view the last 10 lines of a file is specifically designed for this purpose, making it both efficient and straightforward. The `tail` command outputs the last part of files, and by default, it shows the last 10 lines. This is particularly useful for monitoring log files or data files that are continuously updated, as it allows users to quickly see the most recent entries without having to view the entire content of the file. In contrast, the `cat` command is primarily used to display the entire contents of a file, which is not ideal for viewing just the last few lines. The `head` command serves a different purpose altogether; it displays the first 10 lines of a file. Lastly, the `more` command displays the contents of a file one screen at a time, which can also navigate through a file but is not limited to just the last lines. Choosing the `tail` command is the most effective way to focus specifically on the end of a file, making it the correct choice for this scenario.
