Linux Foundation Certified System Administrator (LFCS) — Question 121

Which of the following commands will print the last 10 lines of a text file to the standard output?

Answer options

• A. cat -n 10 filename
• B. dump -n 10 filename
• C. head -n 10 filename
• D. tail -n 10 filename

Correct answer: D

Explanation

The command 'tail -n 10 filename' is specifically designed to show the last 10 lines of a file, making it the correct choice. In contrast, 'cat' and 'dump' do not provide the desired output of the last lines, and 'head' retrieves the first lines of the file instead.
