Exam LX0-103 topic 3 question 40 discussion

The command that will print the last 10 lines of a text file to the standard output is D, tail -n 10 filename. Here's how it works: tail is a command-line utility that outputs the last part of a file. -n is an option for tail that specifies the number of lines to output from the end of the file. 10 is the number of lines that you want to output. filename is the name of the file that you want to output lines from. So, the overall effect of the command is to output the last 10 lines of the file filename.
