The pushd command takes your current directory and "pushes" it into a list for later, then it changes to another directory. It's like saying, "Save where I am, then go here."
The popd command takes the last directory you pushed and "pops" it off, taking you back there. Finally, on Unix pushd, if you run it by itself with no arguments, it will switch between your current directory and the last one you pushed. It's an easy way to switch between two directories. This does not work in PowerShell.
You already know this, but remember that mkdir -p (on Linux/macOS) will make an entire path even if all the directories don't exist. That's what I did very first for this exercise.
Remember that Windows will make a full path and does not need the -p.

• Use the cp -r command to copy more directories with files in them
• Notice how sometimes I put a / (slash) at the end of a directory? That makes sure the file is really a directory, so if the directory doesn't exist I'll get an error.

mv:Moving files or, rather, renaming them. It's easy: give the old name and the new name.

This is one way to look at the contents of a file. It's useful because if the file has many lines, it will "page" so that only one screenful at a time is visible. In the Do More section you'll play with this some more.
