Exercise 2

When you finish Exercise 1, navigate to the directory above the my_folder directory and delete all the content you generated in Exercise 1 with one command.

WARNING: The rm command is DANGEROUS. You can't undo this command. The effects are permanent. Ensure you are in the correct directory and are using the right name of the directory you want to delete. Check three times!

Solution

$ cd ..
$ pwd   # Use to check where you are
$ ls    # Use to verify my_folder exists
$ rm -R my_folder

To repeat, use extreme caution when using the rm command. It's destructive and irreversibly deletes folders and files. That's why we use pwd and ls to ensure what we're about to do is being done where it should be done.

Code Blocks

You can write code blocks using three backticks (```) followed by the language you want to show. For instance, if you wanted to write a Ruby code block you would write:

```ruby
class Foo
end
```

class Foo
end

You can also leave out the language identifier, doing this will make it so your code isn't highlighted at all, and all text will be white with no coloring.

```
class Bar
end
```

class Bar
end

Highlighting

You may highlight lines within your code blocks. This is a different type of highlighting, and isn't related to how the code within your code block may be colored depending on the language identifier used.
To highlight one or more lines of code, add # highlight on a separate line just before the first line you wish to highlight. To end highlighting, add # endhighlight on a separate line immediately after the last line you wish to highlight.

```ruby
def say_hello_world
# highlight
  puts 'Hello World!!!'
# endhighlight
end
```

def say_hello_world
# highlight
  puts 'Hello World!!!'
# endhighlight
end
