hello.txt is NOT working

I type:

grep this hello.txt

and nothing.

I type:

grep e hello.txt

and nothing.

I type:

cat hello.txt

and nothing..

hello.txt DOES appear when I type "ls -l".

What's going on?

Are you doing it within the treehouse workspace or on your on computer which is running a unix system ? This might seem silly as question, but on my side, I've just launched the treehouse workspace linked to this particular video and indeed when I type the command :

ls -l

I have as output, documents & hello.txt, so the grep command is working well to retrieve the words I want to find within the file when I use it.

However if you are on your own machine, be sure the hello.txt is filled with some text... Maybe you 've forgotten this step. Maybe you could try to launch another treehouse workspace, or simple create a new file within it, fill it with some text, and try again the grep command...
