macOS GetFileInfo noob question

Im trying to use this command but terminal tells me it cant refer to the file.
This is what I am typing in...

/Developer/Tools/GetFileInfo -c file.jpg

Now I think well maybe I need to type in the whole path to file even though the examples dont show it so...

/Developer/Tools/GetFileInfo -c /Users/johnblack/Desktop/file.jpg

But still no joy, is it syntax or just the wrong info Im putting in here?

Cheers

wow, noobs get ignored around these parts...

Hey thanks for spending some time on my problem, I will try what you said and let you know how I go.

Thanks again 🙂
