Project: lb_head

In Unix, the head utility is used to display the first N bytes or lines of each of the specified files.

The objective of this project is to write a Node.js command-line script that partially reimplements the head utility.

Here are the general instructions to complete this project:

1. The script must be named lb_head.js.
2. The script must be written in Node.js.

$ node lb_head.js [-h] [-n count | -c bytes] file ...

Where:

• -h, --help is an optional flag used to output the script synopsis.
• -n, --lines is an optional flag used to print count lines of each file. Defaults to 10 if omitted.
