About this interactive
A directory is what the command line calls a folder: the same thing, shown as text instead of a picture. The prompt tells you where you are. C:\Users\demo\Desktop> means you are in Desktop, inside demo, inside Users, on the C drive.
The commands from the lesson:
- cd (change directory) followed by a name moves you into that directory, inside the one you are in.
- cd .. moves you back up one level, to the directory that holds the one you are in. cd ..\.. goes up two.
- A path that starts with a backslash (Windows) or a slash (Linux) starts at the top of the drive, wherever you are now: cd \Users goes to C:\Users.
- mkdir (make directory) creates a new directory.
- pwd (present working directory) prints where you are on Linux.
Windows puts a backslash (\) between directory names; Linux uses a forward slash (/). Linux is also case sensitive, so Desktop and desktop are different names there.
Where an answer is a whole path, type it as the prompt would show it, without the >. Capital letters do not matter to the checker.
