How to change the number of lines?

To change the number of lines displayed by the head command, you can use the -n option followed by the desired number of lines. Here’s how to do it:

Syntax

head -n [NUMBER] filename.txt

Example

If you want to display the first 15 lines of a file named example.txt, you would use:

head -n 15 example.txt

Additional Notes

• You can also use a plus sign (+) to display lines starting from a specific line number. For example, head -n +5 filename.txt will display all lines starting from the 5th line to the end of the file.
• If you omit the -n option, the default is 10 lines.
