There are two ways of looking at github content, the "raw" way and the "Web page" way.

raw.githubusercontent.com returns the raw content of files stored in github, so they can be downloaded simply to your computer. For example, if the page represents a ruby install script, then you will get a ruby install script that your ruby installation will understand.

If you instead download the file using the github.com link, you will actually be downloading a web page with buttons and comments and which displays your wanted script in the middle -- it's what you want to give to your web browser to get a nice page to look at, but for the computer, it is not a script that can be executed or code that can be compiled, but a web page to be displayed. That web page has a button called Raw that sends you to the corresponding content on raw.githubusercontent.com.

To see the content of raw.githubusercontent.com/${repo}/${branch}/${path} in the usual github interface:

you replace raw.githubusercontent.com with plain github.com
AND you insert "blob" between the repo name and the branch name.

In this case, the branch name is "master" (which is a very common branch name), so you replace /master/ with /blob/master/, and so

https://raw.githubusercontent.com/Homebrew/install/master/install

becomes

https://github.com/Homebrew/install/blob/master/install

This is the reverse of finding a file on Github and clicking the Raw link.

The raw githubusercontent com domain is used to serve unprocessed versions of files stored in GitHub repositories  If you browse to a file on GitHub and then click the Raw link  that s where you ll go   The URL in your question references the install file in the master branch of the Homebrew install repository  The rest of that command just retrieves the file and runs ruby on its contents
