So I have been wondering what the name of this key "|" was ever since I learned about or in c++ which is used declared as || so the little vertical hyphen.... what is its actual name?

What, the pipe symbol? It's... pipe. It can be called other things, as this article indicates, like, most simply, vertical bar, but those other names are stupid. It's a pipe.

Code: Select all

ps -ef | less

That's a very common example of piping one UNIX/Linux command to another, one of the uses of pipe.

So, if two men walk into a bar, was it really a |?
