I'm not sure how accurate StatCounter is, given that most Linux users use adblockers. However, according to it, Linux has almost a 14% desktop share in India.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I dunno if that particular one is safe or not, but running a webpage as a script is asking for it.
Could be swapped to something else at any moment, and what you see if you browse to it may not be what is returned if you use the command line...
Downloading the script and checking if it's the same script as the one on github is definitely better. Or running the curl but on raw.githubusercontent.com adress, because then you can be pretty sure it's not something else than you see.
