Problem with open and rm

The script that follows is a cut down version of one that came from elsewhere.


cp /tmp/x.html /tmp/$$.html
ls /tmp/$$.html
[ "$DISPLAY" ] && open /tmp/$$.html
ls /tmp/$$.html
rm -f /tmp/$$.html

I'm on an Imac with OS X 10.6.6. If I run the script as it stands, the open 
tries to open /tmp/$$.html in a new tab in the Safari browser and fails with 
the message: No file exists at the address “/tmp/13551.html”. The terminal 
output is the following pair of lines, which suggest that the file is still 
around after open failed:


If I comment out the final 'rm' line and run it again, I get what I want 
displayed (and a similar pair of lines on the terminal) but unfortunately the 
temporary file is left lying around.

My two questions are: 
How can I change the script so that I can both view the file and have it
