No new commands this time. Build a folder called band, put a file of instruments inside it, then read it back sorted and counted, using only what you already know.
Two things worth noticing as you go. First: echo "Guitar" > band/instruments.txt makes the file inside band without you ever walking into it, because a path works anywhere a filename does. Second: one > followed by two >> is the pattern for building any file up, line by line.
Everything you have done in this course (make a folder, write files, read them back, sort and count them) is what people do in a terminal all day long. Next up: putting these same commands into a file, so the computer can run them for you.
