But there is a tool that is available in the command line (Terminal based) on Linux Operating Systems.
That is youtube-dl, this is a python based code and can be executed in linux OS without any hassles.

youtube-dl in windows or Mac OS can be achieved by installing python interpreter and try it.

for installing in linux, the command is
$prompt] sudo yum install youtube-dl (in redhat or centos or fedora)
$prompt] sudo apt-get install youtube-dl (ubuntu or linux mint)

In ubuntu, you can update the sudo package before installing the youtube-dl.

the above command will download the video in the best possible format. See the image below.
The video downloaded is of the format webm (Its a Web Movie format from Google for optimized view in web browsers)

or copy the above line in /etc/profile.d/ (this will be set for all the users of the computer, also need root password)
