18## Forward
19Every month, Linux Academy releases courses for free. I'm a very busy
20college student and don't have time to whirl through everything I want
21to before it goes behind their paywall again so I figured out how to
22download a course or two every month using
23[`youtube-dl`.](https://github.com/ytdl-org/youtube-dl/)
24
25## Setup
26* Install
27 [`youtube-dl`](https://ytdl-org.github.io/youtube-dl/download.html)
28* Make sure you have a browser handy
29* Create a community account on Linux Academy
30* Get some food
31* Maybe a drink
32* Sit back down in your chair
33* Spin around a bit
34* Read on
35
36## Downloading
37* Log into your account
38* Pick the course you want
39* Open the developer console and go to `Network` (Ctrl+Shift+E in
40 Firefox)
41* You'll want to select `Media` as shown in the screenshot below
42
43*In moving my posts around, this screenshot has disappeared* :shrug:
44
45* Click the video you want to start with
46* Watch the network logs
47* You'll see an entry that starts with `playlist` (screenshot below)
48
49*In moving my posts around, this screenshot has disappeared* :shrug:
50
51* Right click it
52* Copy the URL
53* Paste it after `youtube-dl` in a terminal:
54
55``` bash
56amolith@poseidon:~ $ youtube-dl https://video-cdn.linuxacademy.com/vods3/_definst_/smil:box/cdnstore/modules/lots-of-stuff-in-here
57```
58
59* Press enter
60* Watch the magic unfold
61
62At a high level, `youtube-dl` is acting like your browser and following
63the `m3u` playlist to download chunks of the file. After it fetches them
64all, it runs them through `ffmpeg` to stitch them together into a single
65video!
66
67I found it useful to open a text editor and script downloading a whole
68course at a time. All you have to do is type `youtube-dl -o` and
69copy/paste it however many times there are videos. Then, copy and paste
70the video title in quotes after `-o` and add `.mp4` to the end (command
71example below). After that, paste the URL. Do that with every video in
72the series, save the script, run `chmod +x <script>`, then `./<script>`
73and (after a bit) you'll have an entire course you can watch at your
74leasure!
75
76``` bash
77amolith@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

80**NOTE:** You may want to set up your directory structure beforehand so
81it's easier to script the process. Here's an example of one of mine:
