I wrote in my last message where it is, but that's only where Preview 
decides to create it; other apps will save it in different locations.

echo sometext | open -f
echo sometext | open -f -a textedit
echo sometext | open -f -a bbedit

It is not an unsaved document, and if you run the scripts above you
