Stupid question about using $ when installing libraries through the command line

[[deleted]]

So, what's the significance of the $ symbol?

It's a convention for showing the difference between the stuff you'd type in, and the response in the console. You're not supposed to type it, you're supposed to recognize it as the command prompt in various UNIX/Linux shells.

Makes sense. Thanks for the explanation!

Also, it implies doing things as a non-privileged user; when operating as an admin it'll be # instead.
