help
help — list of commands. It is one of the commands you type in a terminal, and everything below is produced by running it: the output, the error you get when it goes wrong, and a terminal you can type it into yourself.
What it prints
Run against a small demo project — the same one you get in the terminal below, so the output is what you will see, not an illustration of it.
$ help lsls — list files and folders Example: ls -a
Other commands
Try it yourself
Same files as above. Nothing here can break, and nothing leaves your browser.
Where you use it
Lessons that have you type help on a real task, rather than read about it.
