Download YouTube Videos in Linux Command Line

Install youtube-dl to download YouTube videos in Linux terminal

youtube-dl is a Python-based small command-line tool that allows downloading videos from YouTube, Dailymotion, Photobucket, Facebook, Yahoo, Metacafe, Depositfiles and few more similar sites. It is written in pygtk and requires Python interpreter to run this program, it’s not platform restricted. It should run on any Unix, Windows or in Mac OS X based systems.

The youtube-dl tool supports resuming interrupted downloads. If youtube-dl is killed (for example by Ctrl-C or due to loss of Internet connectivity) in the middle of the download, you can simply re-run it with the same YouTube video URL. It will automatically resume the unfinished download, as long as a partial download is present in the current directory. Which means you don’t need download managers in Linux just for resuming downloads.

How to install youtube-dl on Linux

youtube-dl is a popular program and is available in the default repositories of most Linux distributions, if not all. You can use the standard way of installing packages in your distribution to install youtube-dl. I’ll still show some commands for the sake of it.

If you are running Ubuntu-based Linux distribution, you can install it using this command:

The version in Debian/Ubuntu is usually old and you might face errors while downloading videos. However, I recommend installing it directly from its source repository.

For any Linux distribution, you can quickly install youtube-dl on your system through the command line interface with:

sudo wget https://yt-dl.org/downloads/latest/youtube-dl -O /usr/local/bin/youtube-dl

After fetching the file, you need to set a executable permission on the script to execute properly.

sudo chmod a+rx /usr/local/bin/youtube-dl

Once installed, you can update it to the latest version using this command. This is helpful when you have been using it for a few months:
