## Forward
Every month, Linux Academy releases courses for free. I'm a very busy
college student and don't have time to whirl through everything I want
to before it goes behind their paywall again so I figured out how to
download a course or two every month using
[`youtube-dl`.](https://github.com/ytdl-org/youtube-dl/)

## Setup
* Install
  [`youtube-dl`](https://ytdl-org.github.io/youtube-dl/download.html)
* Make sure you have a browser handy
* Create a community account on [Linux
  Academy](https://linuxacademy.com/join/community)
* Get some food
* Maybe a drink
* Sit back down in your chair
* Spin around a bit
* Read on

## Downloading
* Log into your account
* Pick the course you want
* Open the developer console and go to `Network` (Ctrl+Shift+E in
  Firefox)
* You'll want to select `Media` as shown in the screenshot below

*In moving my posts around, this screenshot has disappeared* :shrug:

* Click the video you want to start with
* Watch the network logs
* You'll see an entry that starts with `playlist` (screenshot below)

*In moving my posts around, this screenshot has disappeared* :shrug:

* Right click it
* Copy the URL
* Paste it after `youtube-dl` in a terminal:

``` bash
amolith@poseidon:~ $ youtube-dl https://video-cdn.linuxacademy.com/vods3/_definst_/smil:box/cdnstore/modules/lots-of-stuff-in-here
```

* Press enter
* Watch the magic unfold

At a high level, `youtube-dl` is acting like your browser and following
the `m3u` playlist to download chunks of the file. After it fetches them
all, it runs them through `ffmpeg` to stitch them together into a single
video!

I found it useful to open a text editor and script downloading a whole
course at a time. All you have to do is type `youtube-dl -o` and
copy/paste it however many times there are videos. Then, copy and paste
the video title in quotes after `-o` and add `.mp4` to the end (command
example below). After that, paste the URL. Do that with every video in
the series, save the script, run `chmod +x <script>`, then `./<script>`
and (after a bit) you'll have an entire course you can watch at your
leasure!

``` bash
amolith@poseidon:~ $ youtube-dl -o "04 - Conclusion and Next Steps.mp4" https://video-cdn.linuxacademy.com/vods3/_definst_/smil:box/cdnstore/modules/lots-of-stuff-here
```

**NOTE:** You may want to set up your directory structure beforehand so
it's easier to script the process. Here's an example of one of mine:
