In this course, you will get the chance to explore the command-line interface (CLI), starting with basics like navigating file systems and working with directories and files. Then, you will use those building blocks to tackle more advanced features and tasks within the CLI. You will also learn to turn basic commands into executable scripts and easily automate common tasks. This course will empower you to put the interface to work, take complete control of your computer, and hack your way to productivity.

Harnessing the Power of the Command-Line Interface



# Using NetCat with scripting


We can use `netcat` to serve files if we combine it with a little bit of shell scripting. Let’s create a file called `hello.txt` with some text:

```bash
$ echo "This is a text file served from netcat" > hello.txt
```

Now, we execute this command to make `netcat` listen for connections on port `8000` and serve the `hello.txt` file:

```bash
$ while true; do nc -l 8000 < hello.txt; done
```

This loops indefinitely, listening for connections on port `8000`, and then reads in the file, sending its contents to anything that connects. Let’s make a request with  `curl`:

```bash
$ curl --http0.9 localhost:8000
```

> `HTTP0.9` is a headerless response, which is why we have to specify a  `--http0.9` flag to make sure `curl` handles it normally.

Use the terminal below to practice these commands.
