Which command prints the last part of a file?

Which command prints the last part of a file?

• A. Head
• B. Tail
• C. Cat
• D. Less

Answer: (B)

Reading the end of a file is what tail does. It outputs the last part of the file, by default the last 10 lines, which is exactly what you need when you want to see the most recent entries or the conclusion of a log. In contrast, head shows the beginning of a file, cat outputs the entire file, and less is an interactive viewer for paging through content. You can adjust how many lines you see with -n, for example tail -n 20 prints the last 20 lines, or use tail -f to follow new additions in real time.
