Syntax

head [- number] file

Practice 1

Let consider the file mybook which holds 16 lines. The following example shows the use of the head command.

# head mybook

This is my first book.

I am trying to a write. Here, I test my skill in writing. I leave 2 lines blank.

You may be wondering Why?

Because, I am a writer and I have to think.

I want to write but nothing seems to be coming out.

I have severe constipation of ideas.

Here because the numberof lines have not been particular, the first 10 lines (default value) of mybook are displayed.
