-O file
--output-document=file
The documents will not be written to the appropriate files, but all will be concatenated together and written to file. If - is used as
file, documents will be printed to standard output, disabling link conversion. (Use ./- to print to a file literally named -.)

Use of -O is not intended to mean simply "use the name file instead of the one in the URL;" rather, it is analogous to shell
redirection: wget -O file http://foo is intended to work like wget -O - http://foo > file; file will be truncated immediately, and all
downloaded content will be written there.

So outputting to - will actually write the files content to STDOUT and then you simply pipe it to bash or whatever shell you prefer. If you script needs sudo rights you need to do sudo bash at the end so the line becomes:

wget -O - https://raw.githubusercontent.com/<username>/<project>/<branch>/<path>/<file> | sudo bash
