To use the -n option with the head command, you specify the number of lines you want to display from the beginning of a file. The syntax is as follows:
head -n NUM filename
Where NUM is the number of lines you want to see, and filename is the name of the file.
Example:
If you want to display the first 5 lines of a file named example.txt, you would use:
head -n 5 example.txt
This command will output the first 5 lines of example.txt to the terminal.
