Many thanks to Greg and the others who replied. I've now added a 'sleep 2' command and everything works as I want. > A proper fix would be for open to allow you some means of finding out > when it has, in fact, "opened" the target, so that you know when it's > safe to remove it.

Unfortunately, -W causes open to wait until Safari closes down and is not suitable since the new window is opened in a tab. Eric Blake suggested using '[ "$DISPLAY" ] && open <(cat /tmp/x.html)' so that rm is not needed. I liked this but it failed with some error message and sleep worked. I'm most grateful to you all.
