I'm new to Linux. I'm trying to make a script that prints something and initiates a shutdown command. This is my script:

```
#!/bin/bash    

echo Hello WOOOOORRRRRLLLLDDDDDDD

echo sudo poweroff

```

Every time I try to run my script,using

```
chmod +x Hello World BASH

```

or
 ./Hello World BASH

however, I get this error message:

```
chmod: cannot access 'Hello': No such file or directory
chmod: cannot access 'World': No such file or directory
chmod: cannot access 'BASH': No such file or directory

```

In general, everytime I try to run this script, the "no such file or directory" error message popped up. How can I fix this?
