12,842 PointsWhat are Pipes?
Referenced video: https://teamtreehouse.com/library/console-foundations/environment-and-redirection/pipes-and-redirection
I'm not understanding what Pipes ( | ) are and what they're doing. I think all it's doing is stringing together different programs and running them all at once, but when/why would that be useful at the console command level? Is it just a time saver?

231,248 PointsPipes connect program outputs and inputs.
As explained in the video: "So what pipe does is it takes the standard output of the process to the left of it and makes it the standard input to the process on the right." This can save you a step where you would otherwise create an intermediate file with one command, and use it as redirected input on another.
So it's both a time and disk-space saver.
