mkdir in Ubuntu does not work

Question

I wrote this command in my editor but no result (no warehouse directory)

sudo mkdir -p /Downloads/hive/warehouse

How do I make this work?

Answer 1

What do you mean by an "editor"? Why would you expect a result from writing something in an editor, instead of the terminal?

And where do you think the folder is created ? Because of the starting /, you are asking Ubuntu to create a directory at the root of your system, not in your home or whatever.
