Cat output of islands.txt i am stuck

This one is a bit fussy, do it like this:

cat islands.txt

it prints out no such file or directory

You can use the ls command to display the files that are in your working directory - that may give you some useful information.

i can see the islands txt and i press cat < islands.txt but still nothing

Could you show me a screen shot of what happens when you type:

cat islands.txt

I used cat islands.txt and it worked for me. Nice tabs
